ASDL parser and CLI for code generation.

ASDL describes the abstract syntax of compiler intermediate representations and other tree-like data structures. Just as the lexical and syntactic structures of programming languages are described with regular expressions and context free grammars, ASDL provides a concise notation for describing the abstract syntax of programming languages. Tools can convert ASDL descriptions into the appropriate data-structure definitions and functions to convert the data-structures to or it easier to build compiler components that interoperate.

Functionality is provided in two crates:

• asdl - parser and api ready to use in code generation. Best suited for code generation with rust code. With quota for example.
• asdl-tera model designed for template processing engines like tera and a CLI for code generation with tera template engine.
