LLSD Python Package

[Signal Linden (Bennett Goble)]

Hello folks,

We finally released a standalone llsd python package:

https://pypi.org/project/llsd/
https://github.com/secondlife/python-llsd

This module contains an API-compliant repackaging of llbase.llsd. The
code is largely untouched, aside from being placed broken out into
sensible sub-modules. Tests have been brushed off and put back into
working order. The PyPI releases should have *.whls, which is another
improvement. :)

Both autobuild and python-llsd are now being developed from GitHub
ahead of most of our repositories. BitBucket and GitHub origins are
being kept in sync until a timeline for migration is arrived at. If
you have PRs, make them on GitHub :)
