DRAFT: ocioarchive enhancements

[KevinJW]

Do not merge this is for comments etc.

I've added a 'minimal mode for ocioarchive, that attempts to add only the files you need for the configuration file given.

To run you just add --minimal to the command line.

as an example here is the result of one of my configurations

-rw-r--r-- 1 kwheatle user 222M Jan 16 21:16 test_archive.ocioz
-rw-r--r-- 1 kwheatle user  19M Jan 16 21:02 test_archive_minimal.ocioz

The full one contains 808773530 Bytes from 246 files the minimal one is 62104478 in 29 files

You can imagine that part of the full directory contains the ACES 1,2 configs amongst other items. and from that the minimal config only needed these

It does not yet handle environments, nor have good documentation or tests and no Python bindings

Would be good to have feedback before pursuing it further. especially as this changes the ABI and API
