Publish code / tools to migrate between versions alongside spec version updates

[mojodna]

Many of the changes we're proposing between versions can be scripted given existing catalogs, so let's make it easier to migrate (and not use that as a disincentive to clean things up as we reach a 1.0).

@mojodna Do you already have some code for this? Otherwise, I'll probably start with this in August on a JS basis...

[mojodna]

Reading back through and I spotted this. No, nothing yet. Did you make any headway in August on it?

[m-mohr]

Unfortunately, other work blocks it. I just have a converter for Collections starting with 0.6.x...

I'll work on this here: https://github.com/m-mohr/stac-upgrade-js
Could potentially be useful for stac-browser as well. Or has STAC browser already a mechanism to work with multiple versions? @kbgg

STAC Browser currently does not work with multiple versions afaik. Cc @vincentsarago

PySTAC will now open up old versions of STAC and convert to latest version, https://github.com/stac-utils/pystac/
