Split the normal tape parser class into two in order to add a new option: a PLL-driven tape parser. Decided to see what happens if I attempt to use that to parse CSW Acorn data.

Another fix to deal with real-time fighting: allow 8 and 18 pulses to be recognised as 1s and 0s. That's because the hand-off from ROM routines to parsing may occur very shortly before the first pulse of a valid sequence, making it look like there's a ghost. A cleaner solution needs to be found, probably revolving around allowing parsers to be attached to tapes and therefore to run constantly.

Adjusted to allow inspect_waves to swallow a gap before a bit if necessary, increasing the opportunities for its call.

Adjusted to make sure that the very end of a tape is properly measured.

Relocated the ZX80/81 concept of a 'file' out from Tape into Data, given that it's an exact duplicate of memory.

Extended explicitly to support a token of lookahead, which is pretty much what was on offer anyway. Also corrected instance variable names, as per better adoption of C++ norms.

Started sketching out a tape parser for ZX80 and '81 files. I think this'll help me to verify whether the .O input is working.

I am instructed that the Oric actually catches only positive transitions, and compares the distance between those to a threshold. So here's an altered version of the tape parser that does that.

Implemented better sync-to-zero and discovered a header counting bug plus, probably, a misleading representation of gaps in the Oric TAP decoder.

Had a quick go at using the Oric parser for static analysis. Found out that synchronisation is lost. Need to investigate.

Made an attempt to consolidate what I learnt of Oric encoding while building this hastily and untidily directly into the Oric implementation.
(while adding support for the slow tape encoding mode)

Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing.

Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine).
