Add JPH/JHC unit tests #207

Closed bitsgalore closed 8 months ago

bitsgalore commented 9 months ago

Requires additional test files, see https://github.com/openpreserve/jpylyzer-test-files/issues/9

Of particular interest:

Images that use parameterized colourspaces (code now remains untested).
Addition images that use the CPF marker (because of this).

Added tests:

Also - the following COD en COC properties are undefined in pure HT codestreams:

resetOnBoundaries
predTermination
segmentationSymbols

Added minOccurs="0" to XSD for these properties to prevent XML validation issues:

A more elegant solution might be to make this conditional on formatEnum (if this is possible at all).
