xcms: use unsigned indexes when looping through unsigned values

Clears many gcc warnings of the form:

uvY.c: In function ‘XcmsCIEuvYToCIEXYZ’:
uvY.c:263:19: warning: comparison between signed and unsigned integer
  expressions [-Wsign-compare]
     for (i = 0; i < nColors; i++, pColor++) {
                   ^
