- Add IS-11 NMOS Stream Compatibility Management support.
- This is superseded IS-11 support #271 which was initially created by @N-Nagorny
…move Flow Compatibility API helper functions into details namespace
…raint Set is a subset of another one
…alue with debug message
…o describe the purpose of the validate_base_edid callback
…amcompatibility_base_edid_handler callback, instead of using exception
…amcompatibility_active_constraints_handler callback, instead of using exception

Why is validate_sdp_parameters redefined? Can Stream Compatability not use the transport file parser initialized in make_node_implementation?

Yes, the same validate_sdp_parameters function can be reused, now fixed.

Hmmm, what's the behaviour if EDID support is set to true in the config? Does this pass any of the EDID tests in the NMOS Testing tool?

Should we worry about the Windows 2022 warning?

Are we guarding against a rational being compared with a scalar, or is that a legal comparison?

"Constraint B has enum keyword when Constraint also has it" perhaps?
