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.
