Rebuild on top of CassetteOverlay.jl?

[oxinabox]

CassetteOverlay.jl is a newer package that does a subset of what Cassette does. In particular it only does the basic overdubbing.

To do it, it uses alternative method tables. Which seems a more robust feature than recursive rewriting of all instances of call in the lowered code.

I think switching over to CassetteOverlay would make this package more robust, and faster and would solve #13
