jpx_compatibility::is_jpxb_compatible

Returns true if the data source is compatible with the baseline JPX specification, meaning that it includes "jpxb" in its compatibility list. Amongst other things, this means that the first compositing layer uses only one codestream, with the following properties:

• The codestream is a JPEG2000 code-stream.
• The codestream can be decoded using only JP2000 Part 1 capabilities, possibly in addition to certain multi-component decorrelation extensions from Part 2.
• The codestream is fully contained within the JPX file.

JP2 files are also considered to be JPX baseline compatible.
