Compute multiple checksums in parallel

CFV can compute several different checksum (i.e. MD5 and SFV) at once, however the process is very inefficient: the checksums are simply computed one after another, meaning that each file is read multiple times. A better approach would be to comupte checksums in parallel, reading each file just once.
This is a major issue when doing 2 checksums on an external 2Tbyte USB drive
