CronosPlus .cpy format support

[arzam16]

CronosPlus has an option to backup a "bank" with its data and indices into compressed .cpy archive. Are there plans to support this kind of a database in the future?

This is what I figured so far:

.cpy files start with either:
"CroArc01CroBdCopy" 03 00
"CroArc01CroBdCopy" 02 00
or
"CroArc01CroOutFormCopy" 02 00

followed by a sequence of:

• DWORD chunksize
• BYTE chunk[chunksize]

The format / encoding of the chunks is not immediately obvious to me. That will require some more work to figure it out.
