Prerequisites
Description
This PR add the support for decoding bitmaps with the compression type: BI_ALPHABITFIELDS.
This is a special kind of bitmap type which was introduced with windows CE: https://docs.microsoft.com/en-us/previous-versions/windows/embedded/aa452885(v%3Dmsdn.10)
This also fixes an issue with a rare edge case, decoding bitmaps with a less than full sized palette.
