Handle Single File Compressed Files

[NotGeri]

This PR should allow single compressed files that aren't archives (such as log.gz) to be uncompressed.

As far as I can tell f1c5bbd made it possible for archiverFileSystem to access the compressed files safely, but only SpaceAvailableForDecompression uses this; DecompressFile does not

This should work with all the compression types mhold/archiver supports

Should fix pterodactyl/panel#5034

Realized that if we just use io's Copy, it won't check quota.

I made it read the stream in chunks and check the quota before writing the next chunk.
This works fine and is far quicker than reading the entire stream, calculating its size and then unarchiving it, but you will only know it failed after a while, and you'll have an incomplete archive.

Any thoughts on this? If it's an issue, I can adjust it to do the same as with other archives, which is slower, but you get a clear warning before it uncompresses anything.
