968184fa7a Greaseweazle: Fix RPM measurement in some circumstances. 
Accumulate number of ticks returned in FLUXOP_SPACE so that they
count towards the total track time.

5e4c7719ff Add support for the interfacing to an Apple Disk ][ 
Some folks may want to use interfaces besides PC/Shugart ones.
Together with https://github.com/adafruit/Adafruit_Floppy/pull/15
and a hand wired board I'm able to read flux from an Apple Disk ][

d303067deb Massive refactor to work in logical cylinders everywhere. The logical/physical 
mapping is now done at the last stage and should, ideally, be automatic. I'm
sure there are bugs everywhere.

33bd912476 Some quality of life improvements for Adafruit generic GW-compatibles 
The addition of the new tcsetattr call fixes a problem where interrupting
fluxengine during a flux read will leave data in the device and/or Linux's
serial buffers, so that the next invocation of fluxengine will fail similar
to
```
Error: command returned garbage (0x27 != 0x0 with status 0x31)
```
(the specific value differs because it's actually flux data)

Merely changing the existing tcsetattr call to specify TCSAFLUSH was not
enough; moving it after the 200ms pause seems to be enough.

Note that it doesn't seem feasible in our USB stack to make DTR reset
the device, since that would take down the USB stack and require a fresh
USB connection.

The addition of the special case for `rlen == 0` in read is for when the
GW-compatible board is reset or crashes and usb-disconnects during a
reading operation. Without this change, fluxengine spins forever at 100%
of a CPU, repeating a read().  After the change, this will cause
the host computer to print messages like:
```
  2.1: 200 ms in 68928 bytes
  3.0: Error: serial read returned no data (device removed?)
```
and exit.

I only tested these changes on Linux (Debian with kernel 5.10) and in
particular I don't know if/how it will work on a Mac.

77257b0989 Support time-based reads for Greaseweazle V24+. 
This substantially speeds up read and verify operations, allowing
only 1.2 revs rather than 2 revs to be read.

45d7b284e3 1) update CI to add zip on commit for quick testing 
2) fix gw readflux command (should be 8 bytes long but was packed as 10)
3) add support for non-gw VID/PID (generic serial port that is gw compatible)
4) manually set/clear DTR on serial port devices - this seems to be essential for tinyusb/arduino CDC

not tested with a gw but ought not to have broken anything!

192427cf80 Finally figure out why Windows wasn't working --- the Win32 ReadFile / ::read

bytes are read. Fixed.
