Batch audio dumping

[hyakki]

Thanks for the research on CC!

I've added support in r1691 for the following decoded Atrac file names:

Code:

            // Use the following alternate file name scheme:
            //       Atrac-SSSSSSSS-NNNNNNNN-DDDDDDDD.at3.decoded
            // where SSSSSSSS is the file size in Hex
            //       NNNNNNNN is the number of samples in Hex found in the "fact" Chunk
            //       DDDDDDDD are the first 32-bit in Hex found in the "data" Chunk

In the "big files" example from Hyakki, this should be:
Atrac-001E8F24-006FB111-1DC0223A.at3.decoded

looks good, i'm going to do some more testing on other games and see if i can get any conflicts
