* YQL-19616: Fix TRegexLexer performancevityaman6 days5-45/+120
| | | | | | | | | | | | | | | | | Fix `TRegexLexer` performance. Now it is just 2 times slower than a reference ANTLR implementation on Release mode, so merged regexes are 3 times better than scan&compare. ![image](https://github.com/user-attachments/assets/4e0cb27a-491d-4dbd-b10a-5725ffa6d902) --- - Related to `YQL-19616` - Related to https://github.com/ydb-platform/ydb/issues/15129 - Related to https://github.com/vityaman/ydb/issues/42 --- Pull Request resolved: https://github.com/ytsaurus/ytsaurus/pull/1278 commit_hash:1529f641172fea13f0d33fbfd06a4827c6efde01
