bitmaptools: dither: get rid of shifts 
this happens to make the occasional FS dither artifact disappear.
I guess `a * b >> 8` and `(a * b) / 256` are not identical.  I'm not
sure if it was just the parens or not, but write the clearer code and
rely on the compiler to substitute an appropriate shift if possible.

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

Additional missing-prototypes fixes 
I think this correctly enables missing-prototypes in atmel-samd
and raspberrypi ports.

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.
