Suggestion: Add TraceExplorer command

[jonesmartins]

Based on the "Trace Exploration through Command Line" function, adding a Trace Explorer command might be pretty handy.

Having read @will62794's tlaplus_animation repo, especially aliases.sh and get_tlatools.sh, one would add a new trace command to tla-bin/bin by:

• Copying tla-bin/bin/tlc to a tla-bin/bin/trace file;
• Changing line 9 of this trace file from ...tla2tools.jar tlc2.TLC to ...tla2tools.jar:tla2tools.jar:CommunityModules-202112291842.jar tlc2.TraceExplorer (or to wherever the latest Community Modules jar file can be downloaded from).

It would require an updated Community Modules jar file, so it'd be necessary to add that to tla-bin/download_or_update_tla.sh.

Maybe I am missing a step? Maybe trace is not necessary, given an alternative command?

Thanks
