ast_name_tracker: track external references in ESM snippets (#105)

Adds a new crate `ast_name_tracker` for tracking declared and shadowed names in ESM snippets. This is necessary to track any statistics on a per-symbol level without aggregating dependencies on the module-level, as it can operate on the source level. --------- Co-authored-by: Max Huang-Hobbs <[email protected]>
