Incompatible with Antlr4-Syntax

[jmwolfe]

Not that this extension should be made compatible, but I spent a few hours trying to figure out why I was not getting any visitor or listener files created when saving my grammar file... it turned out it was the Antlr4-Syntax extension which I had also installed alongside this one.

Completely a n00B to Antlr, I thought it couldn't hurt to have both, right?

Perhaps you could mention it in the generation doc or in known issues. I'll also add an issue in that repo.

Just to see I get this right: you say that vscode-antlr4 does no longer generate listeners and visitors when additionally the antlr4-syntax extension is installed?

I don't see how that could affect vscode-antlr4. Everything needed for generation is brought it by antlr4ng-cli node package, odd.
