Reworked project structure for new binary.

Pre-emptively bumped version to `2.0.0`.

rematch compiles and links correctly. repatch also links to rematch correctly.

Documented manifest: We don"t want LTO to be off, and we don"t want more than 1 codegen unit: The project is now split over multiple crates so cross-crate optimisation is needed or there may be a performance regression in rematch.

Fortune for rematch's current commit: Future curse − 末凶
