This makes the auto soft-reset behaviour of mpremote more logical, and now
configurable via these new commands.

When a task waits on a ThreadSafeFlag (and the wait method returns), the
flag is immediately reset. This was not clear in the documentation, which
appeared to copy the description of the wait method from the Event class.

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.

And how they relate to MicroPython. As these features are implemented (or
the decision is made to not implement them) the tables can be updated to
document the differences between MicroPython and standard Python.
Save and restore the same duty cycle when the frequency (or frequency
resolution) is changed. This allows a smooth frequency change.
Also update the esp32 PWM quickref to be clearer.
If MICROPY_PY_SYS_PATH_ARGV_DEFAULTS is enabled (which it is by default)
then sys.path and sys.argv will be initialised and populated with default
values. This keeps all bare-metal ports aligned.

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.
The third and fourth parameters in display.rect() and display.fill_rect()
are not x,y coordinates, but are instead width,height values. Update the
comment after the example to show the correct x,y coordinates of the bottom
right corner of each rectangle, respectively.
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.
