TRD and SCL diskette file formats - ZX Spectrum core

[QuakerRUS]

I think it shall be good if you will add TRD and SCL diskette file formats compatibility.

[Asnivor]

The TRD and SCL file formats were I believe created for storing Betadisk/TR-DOS disk images.

Currently ZXHawk does not emulate the Betadisk interface, or indeed the Pentagon or Scorpion clones that run TR-DOS.

These 2 formats will hopefully be added when I get round to Pentagon emulation, but there is no timeframe for this as yet.

RetroArch supports this in its Fuse core.
