TI-99/4A & Geneve 9640 Floppy Enhancement request #341

Would be nice to have the TI-99 supported disk formats added to be native so we don't have to convert to HFE. We would then be able to verify sectors.

40 Track: TI-99 / Geneve (Single Sided / Single Density 90k) 1 head bps 256 Tracks 0-39 9 sectors per track

TI-99 / Geneve (Single Sided / Double Density 180k) Tracks 0-39 1 heads bps 256 18 sectors per track

TI-99 / Geneve (Double Sided / Single Density 180k) Tracks 0-39 2 heads bps 256 9 sectors per track

TI-99 / Geneve (Double Sided / Double Density 360k) Tracks 0-39 2 heads bps 256 18 sectors per track

80 Track:

TI-99 / Geneve (Double Sided / Single Density 360k) Tracks 0-79 bps 256 9 sectors per track

TI-99 / Geneve (Double Sided / Double Density 720k) Tracks 0-79 bps 256 18 sectors per track

This can usually be probed from the boot sector right? I have a ti99 handler in FlashFloppy that does this, for image files with suffix v9t9.
