fix: support .arr, support ios/wasm binaries

[iaincoulter]

Code changes to include .aar in list of zip type files. AAR is an android archive
Binary file signatures for different apple mach_o/universal and arm support.
Binary file signature for WASM binary

Later change as realised some machines use "file" in version_scanner which i had not handled. Fixed "file" method so it also handles WebAssembly and backup python code handles various Mach-O formats and Webassembly via regex in file.py

This is looking good; thanks for thinking to add this support. Could you add some tests for each signature? Probably the easiest is to add a few tiny mostly-empty archives into test/data (I think our current tests are often metadata + a text file) but you might be able to do some magic with pytest and mock to fake it, or have the test generate the file.
