Add data processing test to CI
Setup tests for CI to include:
- Checking elastic peak reconstruction.
- Elastic yields
- ...
We need to setup a standard set of raw data files (outside of the repository) which can be downloaded and processed
- To start we should get a list of recent elastic runs
- Write a simple script to select elastics
- Plot vs theta and find the peak.
- Check that the angle matches the expected angle (within tolerances)
- Do the same for momentum.
