Description

Several pattern matches can be rewritten directly using a combinator on either `Option` or `Result`, in a  manner similar to ARROW-7692. The pattern-match equivalent often takes a lot more real estate ton convey the same meaning, especially since the combinators in question (`flat_map`, `map`, et al.) are defined in the same way across languages (Scala, Python ...).
