* Fixes for #4321, #4322 * Update README.md Warnings fixed. * Fixes for #4324, adding ports. * Fix Antlr4ng, CSharp, and Java ports. Change Deque to Stack to clarify port code. * Add TypeScript port, fix symbol conflict for TypeScript port. The TypeScript port generates `any_name._list()` accessor method for alts with multiple `any_name` references. This conflicts with the symbol reference `any_name_list`, which is another production. * Fix Cpp target. * Try to get Mac to behave. * Not sure what happened. Try again. * Try3. * Add Dart target. * Add Python3 target. * Add JavaScript port. * Fix Go port. * Add blurb on target agnostic to readme. * Clean up. Force rebuild of Macos Java.

I am now writing every port for the PostgreSQL grammar. But, I'm finding that the grammar is not Target Agnostic
In PostgreSQLLexer.g4, checkLA('-') cannot be target agnostic because not all languages can automatically cast a character literal (or string literal)
'-'to an integer (e.g., JavaScript).All actions in the .g4's must be parameterless method calls.
