Another format that takes really long to unpack (found via fuzzing)

Here's another troublesome file... just 113 bytes, but it takes 1.5 minutes here until ancient is done processing it. Unlike #60, I think this one is not encrypted (the call stack shows it is handled by CompressDecompressor). Maybe this one can be improved as well?

id%3A000009,time%3A0,execs%3A0,orig%3Aid%3A002214,sync%3Afuzzer01,src%3A002196.zip

It is essentially an accidental decompression-bomb. (decompressed size before failure was around 1G) I'll add max-checking and while at it, I'll see where else it is missing

And it was actually a bug. Also yesterdays px20 fix was broken one. fun fun

Looks good, both files fail very quickly now :)
