CUSE in devcontainer

This is a test to see if it is possible to set up a character device in userspace, within a devcontainer running in GitHub Codespaces

The example is taken from libfuse:

• https://libfuse.github.io/doxygen/cuse_8c.html

Getting started

1. Create a new codespace
2. Open the terminal (Ctrl/Cmd + J)
3. Run make
4. Run ./main -d -n test

A new character device should now appear as /dev/test. This just works as a buffer that you can read and write from, as if it was a file.

5. Run echo "hello world" > /dev/test
6. Run cat /dev/test

This should output hello world to stdout
