dsp/lossless.c: clear int sanitizer warnings

Browse Source 
add explicit casts in calls to ColorTransformDelta()

clears warnings of the form:
implicit conversion from type 'uint8_t' (aka 'unsigned char') of value
254 (8-bit, unsigned) to type 'int8_t' (aka 'signed char') changed the
value to -2 (8-bit, signed)
