Subject: [PATCH] fix: Further optimize Color to_lower_ascii

one less branch, and it really shows on microbenchmarks:
https://quick-bench.com/q/pxrI9X9kVtpApj4iIeYnolxgfz4
- 1.6 times faster than https://github.com/opentibiabr/otclient/pull/1490
- 7.2 times faster than the original pre-1490 tolower.
