Add support for .ccd, .chd, .mdf formats about psxpackager

[RupertAvery]

Thanks for using PSXPackager.

It would be nice to support these, but they are not open standards and I have difficulty finding documentation about the file formats.

For CHD, could you not just shell out to chdman?

For example, if you get a CHD as an input file, use chdman extractcd to extract the contents to a temporary folder (which will likely result in BIN and CUE files) and then work on that.

If someone wants to convert to CHD, create BIN and CUE files and then use chdman createcd to generate the CHD.

CHD has a standalone library: https://github.com/rtissera/libchdr
CCD is a different type of cuesheet used by CloneCD. You may find out how they're structured by looking at DIC's source:
https://github.com/saramibreak/DiscImageCreator/blob/master/DiscImageCreator/output.cpp (just search for 'writeccd')

This could become possible with https://github.com/HeatXD/chdr_cs, which are automatically generated bindings for libchdr
