rec: Refactor Protobuf options, add query/response selection

- Turn the protobuf options into a table because there are already
too many of them
- Split the masks applied to the initiator to a separate
`setProtobufMasks` directive
- Add the possibility to log only queries, or only responses
- Add the possibility to select queries (FFI only) and responses
for export from the Lua hooks
- Add regression tests for the protobuf features
