Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed.
...
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

...
Introduces a bunch of further asserts, which aided me in determining the fix, i.e. that Drives being responsible for their own setup_track could double-pump the event loop.

Mostly lifted from DiskController. `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.

Attempts better to hide C1540 implementation details from the reader.

In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Reformulates the Oric more cleanly into the modern world.
...
Specifically: now that the implementation is contained within the CPP file, there's no need to embed the keyboard, tape player and VIA port handler as private classes. Also the pain of additional syntax is reduced, so the keyboard has been bumped up to a fully data-hiding class. I've also transferred overall ownership of the tape player, AY and keyboard up to the Oric itself, with the VIA merely being wired to them, and added a whole bunch of extra documentation.

Tidies the 6502 template and folder hierarchy.
...
Specifically: there's now just the one .h file at the top level, giving a clear indication of what a user should read. That separates implementation from interface. It also devolves a lot more to the base class because doing so makes debug builds less of a hassle. The all-RAM 6502 has been shuffled off into a subfolder, to indicate that it's not something you necessarily need know about. Also general documentation improvements have been applied: incorrect citing of the recurring-template pattern has been removed and the meaning of the two BusHandler methods has now accrued at the bus handler.

Eliminates potential cyclic entry into CSMachine during its -dealloc.

Explicit cause: dealloc calls close_output(). That may decide to flush work, indiscriminately. Some of the flushed work might be audio generation. Audio generation might cause the audio queue to react with an out-of-data announcement. Which would cause a fresh attempt to update the CSMachine.
