Backporting Mac compatibility to BCML

[neebyA]

Hi,

There aren't any actions to take for this issue, I'm only creating it for visibility. Please feel free to close it after a few days.

A while back I had found this script to convert mods for Switch, but it needed BCML's Python API, so I couldn't use ukmm. After ukmm and BCML's common dependencies were updated for Mac support, it became possible to do the same for BCML. I had made the necessary changes to BCML to run on macOS, but wasn't able to upstream them before BCML stopped accepting PRs.

I realize ukmm has superseded BCML, but looking at some recent issues like NiceneNerd/BCML#528 or NiceneNerd/BCML#454, I see there may have still been some interest in installing BCML on a Mac. I pushed the changes for macOS compatibility to my fork, and uploaded the pip install-able binaries under Releases, in case anyone else has a similar niche use case as I did, or just wants to check out the old mod loader on a Mac.

Cheers
