The keyword "af" has been deprecated for some time and "alt" should be used
instead (but "af" still works).

This allows encoding things (eg a Basic-Auth header for a request) without
slicing the \n from the string, which allocates additional memory.

The new ADC methods are: init(), read_uv() and block().
The new ADCBlock class has methods: init() and connect().

Some devices, eg BNO055, can stretch SCL for a long time, so make the
default large to accommodate them. 50ms matches the current default for
stm32 hardware I2C .

The bit-bang implementation was replaced with the RMT implementation in
599b61c086. This commit brings back that
bit-bang code, and allows it to be selected via the new static method:
esp32.RMT.bitstream_channel(None)
The bit-bang implementation may be useful if the RMT needs to be used for
something else, or if bit-banging is more stable in certain applications.

The methods duty_u16() and duty_ns() are implemented to match the existing
docs. The duty will remain the same when the frequency is changed.
Standard ESP32 as well as S2, S3 and C3 are supported.
Thanks to @kdschlosser for the fix for rounding in resolution calculation.
Documentation is updated and examples expanded for esp32, including the
quickref and tutorial. Additional notes are added to the machine.PWM docs
regarding limitations of hardware PWM.
This commit swaps the dimensions of the `framebuffer.FrameBuffer` in the
docs example from 10x100 to 100x10 pixels to avoid clipping.
This is done to better fit the subsequent example code, which writes
text of size 96x8 followed by a 96x1 horizontal line.
The y coordinate of the horizontal line is also adjusted such that it is
drawn inside of the new canvas bounds.
This achieves a substantial performance improvement when rendering glyphs
to color displays, the benefit increasing proportional to the number of
pixels in the glyph.
This allows the write to trigger a notification or indication, but only to
subscribed clients. This is different to gatts_notify/gatts_indicate,
which will unconditionally notify/indicate.

Anywhere a module is mentioned, use its "non-u" name for consistency.
The "import module" vs "import umodule" is something of a FAQ, and this
commit intends to help clear that up. As a first approximation MicroPython
is Python, and so imports should work the same as Python and use the same
name, to a first approximation. The u-version of a module is a detail that
can be learned later on, when the user wants to understand more and have
finer control over importing.
Existing Python code should just work, as much as it is possible to do that
within the constraints of embedded systems, and the MicroPython
documentation should match the idiomatic way to write Python code.
With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users
can consistently use "import foo" across all ports (with the exception of
the minimal ports). And the ability to override/extend via "foo.py"
continues to work well.

Optionally enabled via MICROPY_PY_UJSON_SEPARATORS. Enabled by default.
For dump, make sure mp_get_stream_raise is called after
mod_ujson_separators since CPython does it in this order (if both
separators and stream are invalid, separators will raise an exception
first).
Add separators argument in the docs as well.

This enables optional support for the hardware UART to use the RTS and/or
CTS pins for flow control.
The new "flow" constructor keyword specifies a bitmask of RTS and/or CTS.
This matches the interface used by machine.UART on stm32 and rp2.
Previously on ESP32 it was possible to specify which pins to use for the
RTS and CTS signals, but hardware flow control was never functional: CTS
was not checked before transmitting bytes, and RTS was always driven high
(signalling no buffer space available). With this patch, CTS and RTS both
operate as expected.
This also includes an update to the machine.UART documentation.

This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class. It builds on the stm32 work of blmorris, #1361.
Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
- master transmit and master receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequency
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
- Pyboard D SF2W
- Pyboard V1.1
- ESP32 with SPIRAM
- ESP32

Add new API for specifying the idle level and TX carrier output level, and
new write_pulses modes of operation. Also fix wait_done documentation
which was inverted and wrong about timing.
With docs and a multi-test using TCP server/client.
This method is a MicroPython extension, although there is discussion of
adding it to CPython: https://bugs.python.org/issue41305
