Use canonical pyparsing names

[dellaert]

Summary

• replace deprecated pyparsing camelCase aliases with their canonical PEP 8 names
• rename Module.parseString to Module.parse_string without a compatibility alias
• update the Python and MATLAB wrapper entrypoints and parser tests

Why

Pyparsing 3 recommends its PEP 8 API. The older camelCase spellings are retained only as backward-compatible aliases and can trigger misleading review feedback or eventually be removed. This change uses the canonical API throughout the project while leaving the accepted .i grammar unchanged.

Impact

Callers of the project parser must now use Module.parse_string. This is an intentional breaking rename; Module.parseString is not retained. DelimitedList remains PascalCase because it is pyparsing's canonical class name.

Validation

• conda run -n py312 python -m pytest tests/test_interface_parser.py tests/test_parser_diagnostics.py tests/test_template_instantiator.py — 73 passed
• conda run -n py312 python -m pytest tests — 110 passed
• git diff --check
• verified pyparsing 3.2.5 in py312

Pull request overview

This PR migrates the project’s interface parser and its callers to pyparsing’s canonical (PEP 8–style) APIs, including an intentional breaking rename of Module.parseString to Module.parse_string. It updates the Python/MATLAB wrapper entrypoints and parser-related tests to match the new API surface.

Changes:

• Replace deprecated pyparsing camelCase aliases with canonical PEP 8 names across the interface parser (e.g., set_parse_action, as_list, nested_expr, string_end).
• Rename the project parser entrypoint from Module.parseString to Module.parse_string (no compatibility alias), and update wrappers accordingly.
• Update parser tests to use .parse_string(...) consistently.
