Enable params from a template using from_yaml()

[doswal]

Since there are 25+ parameters for NOAA search functionality, keeping a track of params through search_studies can be difficult. This can be streamlined using from_yaml() method which reads from a templated yaml file.

Proposed Workflow:

• Keep a yaml template with params as keys.
• Use comments to explain what each yaml key/param represents (already present in help(search_studies))
• using from_yaml method, parse the params and initiate search_studies with params = yaml_params.

Note: The params from the. template can not be altered, appended or removed.
