[Feature Request]: custom suffix format

[Alvazz]

Feature description

Is it possible to support compression of a custom suffix format? For example, I compress a folder named "test" into "test.myfiledata", and then decompress the "test.myfiledata" file to finally get the initial "test" folder.

Hi!
The library doesn't limit the archive file extension, either when compressing or extracting it, so you should be able to use any suffix format for the archive file!
