*NOTE:* This is currently built using a custom version of ANTLR4, modified to output visitor structure for Golang (github.com/sheik/antlr4).
If you wish to try it out you will need to check out the custom antlr4 and edit the go.mod replace statement to point Go at it. You will
also need to build the custom antlr4 tool in order to run it.

There is a PR for merging this into the official ANTLR4 repository here: https://github.com/antlr/antlr4/pull/3299
