Can we uncomment some of the named-constant definitions in ParameterGroupNumber.PGN class?

[grant-allan-ctct]

The ParameterGroupNumber class has an inner class PGN which defines a bunch of useful PGN constants.

But some of them are commented out, for example SOFTWARE_IDENT (which has value 0xFEDA).

I am wondering whether there is a reason for them being commented out, versus perhaps we can uncomment them and make them available for people to use?

The current situation makes things interesting when trying to develop code to work with the library. As a workaround, I have defined my own subclass of ParameterGroupNumber.PGN class which fills in some of the blanks, but I would prefer to submit a PR so that it can be fixed in the library itself, unless someone knows of a reason for leaving things as they are...?
