Resolves <https://github.com/askama-rs/askama/issues/442>. The performance is actually slightly better than before. `unicode-ident` is highly optimized and jump free. One test from a fuzzer outcome had to be deleted, because it contained identifiers that weren't actually identifiers. There is still a test that tests the same problem, but every identifier is simply `x`. In another fuzzed test a character [`U+E0049`] was removed.
