Saving fit files?

[jcborras]

Not actually an issue but a feature request: I can't seem to find a way to make (write) a FIT file from a list of records.
Typical usage scenario: data merge from some GPX/TCX source.
I can open a FIT file using python-parse and I could even add records with the missing information but I can't find a method to write a FIT file out of the updated list of records.
Thanks in advance.

Duplicate of #8 some alpha code is in the PR #58 (not merged yet).

I dare to reopen the issue since #8 scope is significantly larger.
Writing a fit file with a different name from just parsed data requires far less work that dealing with (for instance) GPX/TCX files since the later involves XML parsing for varied document entities and possible extensions enduring the shortcomings of python libraries for (again for instance) dealing with XML namespaces. Been there.
Just saying.

IMO #8 is mostly about saving fit file, maybe some simple CVS or JSON parsing. It's not intention of this tool to do TCX or any other elaborate data format parsing, it should stay with low level FIT operations. So So I vote to merge these feature requests and close one as duplicate. @dtcooper what are your thought about this?
