EOPlus Parser/Lexer for Rust

This crate can parse EOPlus input into Quest data structures. It is built from the eoplus-antlr4 grammar written by @cirras.

Currently in use by reoserv for quest parsing.

Issues

Currently quests with invalid syntax will parse without error. The antlr4-rust crate dumps some errors to the console but this crate assumes that everything is fine. I plan to fix this in a future release.
