Updating Cap'n Proto schema

When modifying a protocol's struct that is used in plugins (such as Signature), you need to update the capnproto schema file and recompile it into the Rust source code. The steps are as follows:

Change src/serializers/capnp/schema/plugin.capnp as necessary
Install capnp tool (it's a C++ binary, commonly available in package managers)
Install Rust support for capnp called capnpc-rust:
1. git clone https://github.com/capnproto/capnproto-rust somewhere
2. cd capnproto-rust/capnpc
3. cargo install --path=.
Then, call capnp compile -orust plugin.capnp (change path as necessary)
The result should be plugin_capnp.rs file: Use it to replace the old src/plugin_capnp.rs.
It needs to be autoformatted (cargo fmt --all)
Modify the serialize/deserialize functions. Check the following PRs for details:
