Add dependency groups: (#270)

all: Install all 3rd party modules that have a red_util

    fastapi: Utils for fastapi/uvicorn

    http: Utils for http requests. Includes a
    request client, cache, & serialization library

Move all utils out of utils/ dir and into std or ext
    (for stdlib utils and "extended" utils for 3rd party modules)
