Load the fuse module in REPLs

Support Feature Requests
1

Describe your feature request
Load the fuse module as part of REPL boot if usage of the fuse library is detected.

What problem(s) would this feature solve?
It would allow creating and testing fuse filesystems on Replit.

Explain what you were trying to do when you came across the problem leading to this feature request
I was attempting to create a filesystem driver with fuse and rust that stores objects as files, since the filesystem on my personal device doesn’t support (among other things) symbolic links and file mode bits.
The exact error message:

    Finished dev [unoptimized + debuginfo] target(s) in 1.97s
     Running `target/debug/mfs source mnt`
fuse: device not found, try 'modprobe fuse' first
Error mounting: No such file or directory (os error 2)

We need fuse set up no matter what, because as far as I know, it’s impossible to detect it during boot.

Does Nix support loading kernel modules as part of a package load? If so, that could be Nix’s job. However, I’m pretty sure that Replit has said that repls run on fuse.
