OMR Search enables searching of sequences of intervals and contours both within neumes and between neumes. The version of MEIParser introduced in #806 calculated only intra-neume intervals and contours. This PR adds the calculation of inter-neume intervals and contours to the parser.
This PR also adds some typing to the test suite to conform with --strict checking by mypy and some additional subtests of MEIParser.
