Milestone Preview: 2022.1.0 #1

This is the first preview release of the rewrite. Considering I wanted to get this done by January, having an initial preview by Mid-March isn't ideal, but it's better than nothing.

It's not really possible for me to write changenotes here because so much has changed - but there's an attempt at a summary in the README of the development branch, which I recommend you read if you're curious.

Note that this release does not include any sort of analysis behavior, but it is, I believe, suitable for use with Il2CppAssemblyUnhollower.

It's also considerably faster (up to a 50% reduction in execution time) at doing the same tasks than any previous build.

Also note that the Linux builds have changed from net6-ubuntu to net6-linux.

This release is not published to nuget, but CI builds can be obtained from my nuget feed.
