Extension trait for controlled trimming of prefixes and suffixes of &str and String.

Provided methods trim only if the given pattern matches exact number of times, otherwise they return the unmodified &str. This can be used for primitive parsing and text analysis.

assert_eq!(Ok("trimmed"), "not trimmed".trim_left_matches_exactly("not ", 1));
assert_eq!(Err("not trimmed"), "not trimmed".trim_left_matches_exactly("very ", 1));
assert_eq!(Ok("trimmed"), "tttrimmed".trim_left_matches_exactly('t', 2));
