Chopped time accumulation out of the default Tape process because it's proving to be sufficiently expensive for a TZX as not to be worthwhile. Introduced a cheaper position capturing/restoring method.

Started sketching out greater support. Mostly TODOs right now, but pulse sequence and pure tone are implemented. I probably also need at least the CSW block to hit everything you might see in a ZX80 or ZX81 tape. Then I can worry about the rest when I have a way to test them.

Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.
