This moves most of the generated tables from the data segment into
the text segment (read-only memory) so that it can be shared between
different processes.
As a bonus side effect we can also remove all casts in the generated parsers.

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
