- Allow initializing in a static, without Forever. - Remove ability to close, since in embedded enviromnents channels usually live forever and don't get closed. - Remove MPSC restriction, it's MPMC now. Rename "mpsc" to "channel". - `Sender` and `Receiver` are still available if you want to enforce a piece of code only has send/receive access, but are optional: you can send/receive directly into the Channel if you want.
