Don't use GNU extension for binary numbers
The dithering code (specifically `dither_factor_bayer_8`) uses a GNU
extension for binary notation, eg 0b001. This is not supported by MSVC
(at least) and breaks the build on this platform [1].
This patches uses hexadecimal notation instead, fixing the build.
