The docs seem to lie about what these methods do.
This is the naive solution since it's my first day looking
at go but would it be possible to get these methods
to marshal to public or private key correctly by passing
a type to them?
* bring back plaintext 2.0.0 with new constructor
* fix deprecation comment
* rm unused context argument
* only check remote id validity if we actually have keys
* bring back msgio & simultaneous read/write
* add plaintext/2.0.0 (with ugly protoc hack)
* gofmt
* gofmt (for real this time)
* add `go_package` option to proto files
* Revert "add `go_package` option to proto files"

* less hacky protobuf imports
* add doc comment for PublicKeyFromProto
* clean up handshake
* go fmt, lol
* use network.MessageSizeMax for ggio reader
