v4.23.0

• Update Aniseed (v3.21.0) and Fennel (v0.10.0).
• Set TERM=dumb when launching subprocesses for stdio REPLs, fixes #232 and Olical/aniseed#53 (I think?).
• Expose the correct fennel module as package.loaded.fennel which is required if you want to use metadata with the compiler. This is now only done if there isn't already a loaded fennel module. Fixes #237.
• Wrote up multiple connections with ConjureClientState to help with #234, others may find it useful!
