Useful utility method

[boxerab]

sharing a useful little utility method that I use to validate the signature read from an ICC profile - with fuzzers, it's necessary to do this sanity check and reject invalid signatures.

bool isValidICCColourSpace(uint32_t signature){
    return    (signature == cmsSigXYZData ) ||
                (signature == cmsSigLabData ) ||
                (signature == cmsSigLuvData ) ||
                (signature == cmsSigYCbCrData ) ||
                (signature == cmsSigYxyData ) ||
                (signature == cmsSigRgbData ) ||
                (signature == cmsSigGrayData ) ||
                (signature == cmsSigHsvData ) ||
                (signature == cmsSigHlsData ) ||
                (signature == cmsSigCmykData ) ||
                (signature == cmsSigCmyData ) ||
                (signature == cmsSigMCH1Data ) ||
                (signature == cmsSigMCH2Data ) ||
                (signature == cmsSigMCH3Data ) ||
                (signature == cmsSigMCH4Data ) ||
                (signature == cmsSigMCH5Data ) ||
                (signature == cmsSigMCH6Data ) ||
                (signature == cmsSigMCH7Data ) ||
                (signature == cmsSigMCH8Data ) ||
                (signature == cmsSigMCH9Data ) ||
                (signature == cmsSigMCHAData ) ||
                (signature == cmsSigMCHBData ) ||
                (signature == cmsSigMCHCData ) ||
                (signature == cmsSigMCHDData ) ||
                (signature == cmsSigMCHEData ) ||
                (signature == cmsSigMCHFData ) ||

                (signature == cmsSig8colorData ) ||
                (signature == cmsSig9colorData ) ||
