Two big changes in this release:
* CMS MiniAOD support (Run 2) is enabled. Only a limited number of collections, etc., are present - need a full type system run for it.
* ATLAS xAOD R22 is also supported. Same problems, however - only a limited number of collections are supported until full type support is enabled (in the front ends). This was done in a way as R21 and R22 code is common - so other than switching the transformer tag, R22 should run without any new servicex installation (and works locally).
There was also a set of work cleaning up the codebase (with lots more to do!). There was also some work done so that one can use `MetaData` to specify the transformer image. This works with `LocalFile`, and will eventually be lit up for `servicex`.
