Constants not returned in DecodedMessage values dict

[michaelpking]

Hi,
I like the library, ease of use is great. We have a common constant field defined across all templates in my project that can be used for semantic grouping however the DecodedMessage value dict doesn't not contain representation of the constant. I'd like to use this library in a project that uses some SBE constant fields however I can see in the code that constants are specifically ignored.
Can the constant value be added to the values dict instead of being ignored?
Thanks,
Mike
