Fixed output precision compared to the new approach of trusting the flywheel for position, and eliminated fixed-Acorn constants. Also re-enabled the faded previous frame, at least temporarily.

Made an attempt to switch to the flywheels for both vertical and horizontal sync, and to act more appropriately for out-of-bounds sync requests. Lots of tweaking to do, I fear.

Switched to generating an interlaced output, that apparently being correct. Enabled a poor man's version of phosphor persistence to smooth things out a little. It's not completely unconvincing.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Simplified further: eliminated delegate. Which means I can go frame-free internally to the CRT at some point, if I want.

Bumped the speaker up to the full namespace, since Tape lives there to avoid delegation complexity. Turned the CRT into something the Electron statically owns, fixing a memory leak by simplifying.
