Step 4: Syntax Highlighting

[gbleaney]

The goal here is to have the plugin turn on syntax highlighting for the two kinds of files relavent to Pysa: taint.config and *.pysa files.

Here are the VSCode docs on syntax highlighting.

For .pysa files, the highlighting should look like exactly what you get in a .py file. As a start, see if we can just get a Python syntax highlighter to passably highlight the file. As a stretch goal, see if you can modify the Python syntax highlighter into treating the fully qualified function name the same as a normal unqualified function name. As a REAL stretch goal, see if you can treat DSL code in .pysa files as an embedded language and highlight it differently

taint.config files are just JSON files, so all you need to do is apply a JSON highlighter to the file.
