Improved `scheme-live` command line tool

[amirouche]

Currently scheme-live command line tool (located in the directory ~scheme-live/local/bin/ allows to:

• install a scheme
• run a program
• start a repl
• run the test suite

And it works only with bash and Debian, and Ubuntu

There is several improvements to be made:

• Rewrite with Scheme
• Make it possible to install a version of a Scheme that we consider stable (at this time it install the latest version from git)
• Make it possible to be installed e.g. in /usr/local/bin/
• Add compile command
• Support more Linux distributions:
  • Fedora
  • Alpine
  • Gentoo
  • Arch
  • NixOS
  • Guix
