pyoxidizer: add hooks to inject extra python packages and install files

We need this type of hook to inject our internal extension and resource files
at Google. Presumably this could be useful to others, so instead of trying to
carry an internal patch we've done this in a modular way that should be of
value upstream.

I'm extremely puzzled by the behavior of glob() on Windows, and I'll
be filing at least one (probably two) bugs upstream about it.

Check upgrade behavior

Right now, sidedata has not upgrade support
