Issue:
Docs: which Cap'n Proto RPC level does this rust implementation satisfy?
Hi there,

I just recently learned about cap'n proto and this library. The [RPC docs page](https://capnproto.org/otherlang.html) for the protocol breaks the total feature set up into 4 "levels" which implementations can advertise in order to succinctly communicate to users how much of the specification it implements.

Which level does this implementation satisfy? And would it be appropriate to add this information to the README?

Thanks!
Oliver


Discussion / hints:
It's a level one implementation. The docs already mention that (though not in the top-level readme):
https://docs.rs/capnp-rpc/0.14.1/capnp_rpc/
