[x3d-public] X3D regexes for colorRGBA, image need work

[Don Brutzman]

Thanks for the analysis, very helpful.

Not ready yet, but I have made progress integrating the JUnit 5 test framework into X3DJSAIL testing.

Once ready, will apply the various/numerous candidate regex tests into pre-release testing.  This will not only help X3DJSAIL but also X3D XML Schema and anything else using X3D Unified Object Model (X3DUOM).
