Due to https://github.com/lalrpop/lalrpop/issues/750, an upgrade to regex >= 1.8.0 causes build failues because the unicode feature on regex-syntax is no longer enabled automatically.
Work around that issue by adding a (otherwise unnecessary) dependency on regex-syntax, enabling the unicode feature.
