staging/color-management: loosen restriction on maxCLL and maxFALL

ANSI/CTA-861-H does not require that maxCLL or maxFALL be within the
Mastering Display Luminance range, and it is common for movies to have a
maxCLL greater than the Mastering Display Luminance. Additionally,
Microsoft's own documentation* contains an example that does not pass
the restriction in the protocol. These values are valid, used in the
real world, and clients should not need to discard them. We keep the
requirement that maxFALL <= maxCLL since that is required, but these
values have no relation to the Mastering Display Luminance.

See #263 for further details on why the restriction on maxCLL and
maxFALL is not desirable. Fixes #263.
