* work

* almost done with command protobuffers

* done translating command data structures

* mid transferring of every command to protobuff command

* transferred plugin_command.rs, now moving on to shim.rs

* plugin command working with protobufs

* protobuffers in update

* protobuf event tests

* various TODOs and comments

* fix zellij-tile

* clean up prost deps

* remove version mismatch error

* fix panic

* some cleanups

* clean up event protobuffers

* clean up command protobuffers

* clean up various protobufs

* refactor protobufs

* update comments

* some transformation fixes

* use protobufs for workers

* style(fmt): rustfmt
