docs/library: Fix framebuf monochrome 1-bit modes, swapping HLSB/HMSB.
This fix can be demonstrated by the following:
b = bytearray(32)
f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HLSB)
f.pixel(0, 0, 1)
print('MONO_HLSB', hex(b[0]))
b = bytearray(32)
f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HMSB)
f.pixel(0, 0, 1)
print('MONO_HMSB', hex(b[0]))
Outcome:
MONO_HLSB 0x80
MONO_HMSB 0x1

Monochrome (1-bit) color format
This defines a mapping where the bits in a byte are horizontally mapped.
- Each byte occupies 8 horizontal pixels with bit 0 being the leftmost.
+ Each byte occupies 8 horizontal pixels with bit 7 being the leftmost.
Subsequent bytes appear at successive horizontal locations until the
rightmost edge is reached. Further bytes are rendered on the next row, one
pixel lower.
