Based on suggestion from @qkaiser. This will make it easier to integrate with unblob (see onekey-sec/unblob#1244).

Should probably think of a better test...

Interesting discussion typing.*IO: python/typing#829
Leaning towards the current list of type options being fine for now, with the option to change it later if needed for e.g. integration with unblob.

I guess it would probably be good to pick a specific version of powertoys.msi eventually so that we know what size to expect here. (Doesn't need to be part of this PR though)

Summary
Based on suggestion from @qkaiser. This will make it easier to integrate with unblob (see onekey-sec/unblob#1244).
Proposed changes
Add mmap as possible input to
Packageand add test cases.I marked it as WIP to see if it makes sense to use
typing.BinaryIOas the type hint (which sounds like it might work from its description). I also left a TODO for actually testing something about the parsed MSI (I didn't havepowertoys.msiso I just used7z).
