bitmaptools: Fix the case where `factor`'s Python type is int
mp_obj_float_get gets the value of an object, which must be
exactly a float.  mp_obj_get_float gets the float value of
an object of various types, including floats & ints.

bitmaptools: use stream API
this allows `readinto` to succeed in the unix port, where the VFS
is not FAT

Jeff Epler eaf8bc0abe bitmaptools: add dither
This can convert a BGR565_SWAPPED bitmap to B&W in about 82ms on
esp32-s2.

Jeff Epler 2ec2761ce0 bitmaptools: add alphablend
This blends two "565"-format bitmaps, including byteswapped ones. All
the bitmaps have to have the same memory format.

The routine takes about 63ms on a Kaluga when operating on 320x240 bitmaps.
Of course, displaying the bitmap also takes time.

There's untested code for the L8 (8-bit greyscale) case. This can be
enabled once gifio is merged.

Rob Capellini b8f2799609 Convert more modules to use MP_REGISTER_MODULE
Convert bitbangio, bitmaptools, _bleio, board, busio, countio, digitalio, framebufferio, frequencyio, gamepadshift, getpass, keypad, math, microcontroller, and msgpack modules to use MP_REGISTER_MODULE.

Related to #5183.

It is required to call .dirty() with appropriate arguments after modifications through the buffer protocol, or the display might not be updated correctly.

Jeff Epler 9133b23a37 bitmaptools: Add readinto
When reading uncompressed bitmap data directly, readinto can work
much more quickly than a Python-coded loop.

On a Raspberry Pi Pico, I benchmarked a modified version of
adafruit_bitmap_font's pcf reader which uses readinto instead of
the existing code. My test font was a 72-point file created from Arial.

This decreased the time to load all the ASCII glyphs from 4.9 seconds to
just 0.44 seconds.

While this attempts to support many pixel configurations (1/2/4/8/16/24/32
bpp; swapped words and pixels) only the single combination used by
PCF fonts was tested.
