68314cd44d Add n88basic format. 
This isn't really intended to be used directly (bare images are
normally .d88 etc) but is useful for testing the FM encoder.

634be4ae51 Fix SCP writer to always write complete revolutions. 
There were a couple of problems that needed to be fixed:

- Fluxmaps can be produced with zero index pulses by encoders.
This is somewhat ambiguous but it's assumed that this means there
is exactly one revolution.

- The SCP unindexed mode wasn't properly supported, as it should
create equal-length revolutions not aligned to indexes. However,
fluxmaps don't contain any information on rotation speed. Therefore,
drop the ability to create unindexed SCPs and slightly change the
meaning of the option to not include pre-index data.

- Real flux reads can potentially produce duplicate index pulses.
Avoid creating zero-length revs.

- Fix off-by-one error for rev count.
