Improved outputs to analyze integration test results

[aspeake]

Fixes https://github.com/trynthink/scout/issues/415

Introduces a class to compare integration test results on a branch with the results stored on master. A previous PR (https://github.com/trynthink/scout/pull/440) added all integration test results to master. This PR provides a way of evaluating the differences between the working branch and master, which include:

• Store plot pdfs as CI artifacts so that they can be visually compared against master
• New script compare_results.py to:
  • Output differences in keys between the branches' agg_results and ecm_results (output to agg_results_key_diffs.csv and ecm_results_key_diffs.csv)
  • Output percent differences in values between the branches' agg_results and ecm_results, as long as values meet an absolute threshold and the differences meet a percent threshold (output to agg_results_value_diffs.csv and ecm_results_value_diffs.csv)
  • Output percent differences in values between branches' Summary_Data-MAP.xlsx and Summary_Data-TP.xlsx (output to Summary_Data-MAP_percent_diffs.csv and Summary_Data-TP_percent_diffs.csv)
• Update the Github Actions workflow so that when there are differences between the branch and master agg_results.json or ecm_results.json, then:
  • Commit new results and plots (same as before)
  • Pull down agg_results.json, ecm_results.json, Summary_Data-TP.xlsx, Summary_Data-MAP.xlsx from master, store in tests/integration_tests/results_base
  • Run tests/integration_tests/compare_results.py
  • Store the output csvs described above as CI artifacts

Example Summary_Data-*_percent_diffs.xlsx: Same format as original xlsx files, but values are the percent differences
