Draft: Resolve #654: Add OMASA smoke tests
Related to #654 (closed), #668 (closed), !902 (merged)
Requires !902 (merged) to be merged before this.
This MR adds the missing OMASA smoke tests. Additionally self tests for MASA and OMASA JBM are added. A pre-processing script is added to smoke tests for generating the combined format inputs from the existing short test vectors.
