Add ResultReference<T> to record_replay library. (#18)

This introduces a level of indirection that will allow
recording objects to differentiate between the invocation
result return value, the recorded result value, and the
serialized result value.

This is used to provide "special handling" of certain
invocation results (such as byte arrays) to make recordings
more human-readable & editable.

This design also yields more technical correctness over
the previous design. This is because we used to delay
recording an invocation whose result was a Future until
that future completed. Now, we record the invocation
immediately and late-record future results (with support
for awaiting those futures when serializing a recoridng).

Another step in #11
