**Problem:** After `ts_parser_parse_with_options()`, the parser options
are still stored in the parser object, meaning that a successive call to
`ts_parser_parse()` will actually behave like
`ts_parser_parse_with_options()`, which is not obvious and can have
unintended consequences.

**Solution:** Reset to empty options state after
`ts_parser_parse_with_options()`.
