Makes an attempt at implementing all missing TZX 1.20 blocks.
Towards that aim, simplifies CSW handling so that even regular RLE compression uses a static grab of file contents.

Switches FileHolder to have a usage much closer to FILE *.
Thereby opens a route for file format implementations such as that appearing for CPC DSK that create an in-memory copy and perform a full rewrite.

Further beefs up the list of chunks that this TZX parser can either comprehend or skip.

Added support for the ID 20 block and fixed a minor error in my skip-the-contents version of block 11: length is three bytes long, not two. This gives me enough structure properly to get to the end of my current test CDT, albeit without making any of the noises.

Made an attempt to obey the proper TZX rules on gaps, and to hit the common-clock-rate Time optimisation.

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.

Spotted that pilot and data segments have different encodings — of course! — and attempted to adapt.

Took a first, incorrect, shot at TZX chunk 0x19, the generalised data block.

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.
