YAML Input Script Capability

[Shockblack]

Describe your changes

Added YAML Ain't Markdown Language (YAML) input specification file support in both EXOSIMS.MissionSim and EXOSIMS.Prototypes.SurveySimulation modules. Checks for the input file extension are added for both JSON (.json) and YAML (.yml and .yaml).

Three new sample scripts are introduced: sampleScript_coron.yaml, test-scripts/simplest.yaml, and test-scripts/simplest-error.yaml. sampleScript_coron.yaml is a YAML version of the quickstart script sampleScript_coron.json in the documentation, while the other two are used to test the MissionSim.py I/O for YAML files.

tests/test_MissionSim.py has been modified to test YAML files as input as well. The script name for the JSON files has also been adjusted for clarity.
