fix: Remove cHRM check to accomodate ACES AP1
ACES AP1 has a red endpoint with a negative Z, this triggers the checks
in libpng that ensure that x, y and z (chromaticities) are all >=0.
This removes the checks on the sign of the chromaticities since it is
valid to use negative values for any of them and converts the "internal"
error code return to external (because the internal cases correspond to
negative x, y or z.)
