TGA images with palettes in 24 or 32 bit now create 32 bit images 

Was creating 16-bit images for those before.
Could also support 24-bit images, but either we need another convert function or another palette for that (the 16 and 32 bit both work with 32 bit palettes, the 24 bit conversion function only with 24 bit palettes)
