Merge branch 'amiranda/53-create-dedicated-server-in-ci-tests' into 'main'

Resolve "Create dedicated server in CI tests"

This MR adds a `scripts/runner.sh` helper script that allows starting and stopping the `scord` daemon from CMake. This in turn allows us to define CTest fixtures to startup and stop the server on demand, upon which RPC tests can depend on. Thus, the `scord` daemon will start automatically when running RPC tests, and will also stop automatically when the tests complete.

Closes #53
