Decided the chunks / ensemble results per thread will be written as jsons and not as raw strings. Changed tests accordingly

Fixing tests that failed. Added a function to filter dicts based on value instead of key. Added M&S data to grid options rather than custom options

remove deprecated resolution setting

Fixed errors for the test_grid tests. I put an extra check on the arguments that are passed into run_system where i catch the ones ending with %d

adding extra testfiles and making sure that there are no imports that arent already in required_packages
