SetSrgbcBC[1-3] Not Defined

[Lin20]

The functions

int CMP_CDECL SetSrgbBC1(void* options, bool sRGB);
int CMP_CDECL SetSrgbBC2(void* options, bool sRGB);
int CMP_CDECL SetSrgbBC3(void* options, bool sRGB);

are declared in cmp_core.h, but don't appear to be defined anywhere. After skimming around, it looks like sRGB is supported in the actual compression kernels, though I haven't tested it after just manually assigning the options directly.

Thank you for this awesome library and all the work that goes into it!
