feat: Adding a diff filter (#193)

* start filter diff
* Refactor the script to compute L1Diff
* test diffFields
* fix setMeshes
* Rename the test file of AttributesDiff filter
* Change bool with enum for the attribute localization
* fix dicSharedAttributes computation
* implementation of inf norm
* Factorize the two diff computation functions in one
* Apply suggestions review
* Add meshes for testing AttributesDiff filter
* Update the test meshes
