General tree sitter grammar for log files

Tree-sitter log

A tree sitter grammar that's trying to be general enough to work through most log files. Mainly inspired by the VSCode extension and this repo. For now it's integrated into Helix Editor, but can be used everywhere you use tree-sitter.

If something is not highlighted as you want, feel free to submit a PR or open an issue.

The most important files are grammar.js and test/corpus/testsuite.log, almost all the rest is generated by the tree-sitter command line tool.
