Fixes delimited methods on Caps & improves perf

* Delimited methods on Caps (`ToSnake`, `ToScreamingSnake`, `ToKebab`, `ToScreamingKebab`, `ToDotNotation, `ToScreamingDotNotation`) were previously not using the instance `ToDelimited` method and thus config was not being used.

* Adds `WriteUpperFirstLowerRest`, `WriteSplitLowerFirstUpperRest`, `WriteSplitLower`, `WriteSplitUpper`, `Write`, `WriteUpper`, `WriteLower`, `WriteRune` to `token` package for a minor perf improvement.

* updates benchmarks
