943deb67ea Generic Support for Session and Lap in FIT files
GENERIC SUPPORT FOR PARSING INTO XDATA

.. Generically parse FIT file messages into XDATA. The current
   implementation does this for session, lap and totals messages
   but could very easily be extended to any other message type

.. Generic parsing uses metadata rather than hard coding the
   message and field types and so on

.. The FIT metadata (FITmetadata.json) has been expanded to
   include definitions of message types and all the standard
   fields within the message types

.. The existing hard-coded parsing remains to extract data
   and apply directly to ridefile samples and metadata. The
   generic parser simply adds additional tabs on the data
   view as XDATA so users can access it.

   CODE REFACTORING, COMMENTS AND BUG FIXES

.. At some point the code needs to be refactored as it is
   janky and needs to align with the rest of the codebase

.. Includes a mild refactor renaming some of the classes/structs
   and variables to reflect what they actually are, for example:

       FitFileReadState -> FitFileParser
       FitDefinition -> FitMessage

.. Added lots of code comments and re-organised the code
   into clear sections to help navigate what is a very
   cumbersome source file, this breaks git blame history
   but is worth the loss (you can checkout an earlier commit
   to do a full blame)

.. Changed debugging levels to be more helpful

.. Generally I did not change any code, but there were a
   couple of serious bugs that needed to be corrected:

      Field definitions gets the type wrong in a couple of
      places since the type is stored in the low 4 bits:
      type = value & 0x1F

      The decodeDeveloperFieldDescription function did not
      check for NA_VALUEs for scale, offset, native field

.. For less serious bugs I added FIXME comments throughout the code

Fixes #4416

Added the tooling to the util directory to generate a
JSON file with product and manufacturer metadata for
use by the FITRideFile decoder.
