feat: await-able Async methods (#1572)

* make each and family awaitable

* dont pretend they're AsyncFunctions

* check errors

* ensure function name is preserved somehow

* awaitable concat

* awaitable detect

* awaitable every/filter

* awaitable groupBy

* awaitable map/mapValues

* awaitable reduce

* awaitable reject

* awaitable some

* awaitable transform

* awaitable times

* awaitable auto

* awaitable compose/seq

* awaitable whilst/until (lol)

* awaitable forever

* awaitable parallel/race

* awaitable retry

* awaitable series (lol)

* awaitable tryEach

* awaitable waterfall (lol)

* lint

* cleanup, remove noop and unused internal functions
