REQ: Add support for fuse-t on macOS

[mbirth]

There's a FUSE replacement for macOS that doesn't need a kext anymore: macos-fuse-t/fuse-t. It's supposed to be a drop-in replacement for osxfuse/macfuse, but just adding find_library('fuse-t') to the list in fuse.py now produces this error when trying to mount my Switch's eMMC:

$ sudo mount_nandhac -d --keys keys/prod_mbirth.keys /dev/disk8 ./fuse
ninfs v1.6.1 - https://github.com/ihaveamac/ninfs
- Note: This should *not* be run as root.
- The mount will not be normally accessible by other users.
- This should be run from a non-root terminal.
- If you want root to be able to access the mount,
-   you can add `-o allow_root` to the arguments.

short read on fuse device

So this might need a few more tweaks, I guess.

The core of this issue may be due to how fuse-t handles parsing options and it not liking a slash. Notice at the end that it's trying to open "/disk8" in the filesystem. This path would have been displayed in the volume name in the form of "Nintendo Switch NAND (dev/disk8)".

I tested this with the 3dsx mount and found that a volname of "3DSX Homebrew (Downloads/FBI.3dsx)" crashes, but "3DSX Homebrew" alone doesn't. Or any other name without a slash.

So what I'll probably do instead is only display the filename and not its containing folder.

By the way you can also set FUSE_LIBRARY_PATH=/usr/local/lib/libfuse-t.dylib to force fusepy to load fuse-t without any source code edits.

0b33c846f6bc8534ec2759fb58ec40ca677fb3df will try to load fuse-t if it can't find macFUSE.
