fix(most-run): check for matching stream types in sinks and drivers

Beyond just checking matching keyof in sinks/sources and drivers, this
commit will type check with TypeScript 2.2 whether the specific stream
type for a sink matches the expected input of the driver, and vice
versa for sources.

BREAKING CHANGE:
If you are using JavaScript, literally nothing changes. If you are using
TypeScript, this version may detect more errors than before, and may
break (by not compiling) your existing code if your existing code
happened to have a sneaky bug.
