Problem: The previous version of the extension only supported
PascaLIGO dialect. We need to add syntax highlighting and
activation events for ReasonLIGO and CameLIGO.
Solution: Add .tmlanguage.json files for ReasonLIGO and CameLIGO,
add activation events.
Problem: We need to deliver a VSCode extension but the one we use
currently is located in a separate repo, requires manual patches
and does not support ReasonLIGO.
Solution: Add our extension that supports PascaLIGO and ReasonLIGO;
CamLIGO is WIP.
