Add remaining Genslip parameters into the codebase

[lispandfound]

Currently we expose a limited subset of genslip parameters in the code base, but we could do to add the rest. Here are the default values in YAML format that I have extracted from genslip_v5.6.2.c:

# Rise time and source time function values

The tasks to complete this feature would be as follows:

1. Add this YAML block into the root defaults.yaml file: here.
2. Update the schema in schemas.py: here.
3. Check that genslip is correctly supplied with these values by running realisation-to-srf with an input realisation. You could probably steal one from Cesar or Ayushi and update it using the migration tool on your new branch. The genslip command is built automatically from the realisation config in _build_genslip_command.
4. Update the test cases in tests/test_realisation_to_srf.py and tests/test_realisation.py to include these new defaults.
