Puts the disk controller back into the loop with knowledge about reading mode, and uses that knowledge to cut off the PLL.

96bf133924
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.

Thomas Harte
6d6cac429d
Fixes extra time accumulation during track running.
...
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 `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.
