rd: a receive whose argument can be set on the fly;
using dynamic patching and iemguts;
;
takes one optional creation arg for the initial receive;
has one inlet which is for sending in a list/name of the new receive

Like iemlib's [iem_receive] or iemgut's [oreceive] ?

Note the following caveat with settable receives: https://github.com/pure-data/pure-data/pull/604#issuecomment-487890771

TL;DR: settable receives work fine most of time, but under specific circumstances they can crash Pd. Use with care.
