Problem installing on Mac with macFUSE

Had problem installing GCSF (from crate) on macOS with already installed fuse, as `pkg-config` was looking for osxfuse which is the old name. osxfuse has been renamed to macFUSE, and is installed as `fuse` (at least on my system, installed using brew in spring 2022).

Solved temporarely by creating a symlink for the `fuse.pc` file to a `osxfuse.pc` file, so that the installer could find the required files. This fixed the install error.

Might be worth updating, so that both `osxfuse` or `fuse` work for `pkg-config`. Until then, the method above worked for me

Locate the build configuration or dependency checks that use pkg-config for osxfuse, then review how the Rust crate handles macOS installation. Reproduce the install with Homebrew's macFUSE, where the package is exposed as fuse, and verify that both fuse and osxfuse setups are handled without a manual symlink.
