Last 4 bytes may be CRC32 #2

I did some work on .pti files and found the last quartet of the header was a CRC32 of the preceding structure. It may be the same here! I will have a go and let you know sometime.

@ejconlon thanks! Would really appreciate it

I checked on a few files and it seems to be the case (in every PT format) that the files have a magic code, fixed length data, CRC32, then any variable length data: https://github.com/ejconlon/polyendtracker-formats

@ejconlon nice find, thanks!
