add CMR graphql functionalities

I agree adding support to query cmr's graphql endpoints should be on the roadmap for this library. IMO, this library should exclusively utilize CMR's graphql endpoints.

I also agree with @mfisher87 that we should utilize some level of code-generation to build out the library.

Perhaps it would make sense to add a cmr.graphql module so this option could be explored without breaking the existing interface? Eventually we might be able to start rewriting the existing functions to just call this new graphql module.

I think based on some discussions during today's hack week @doug-newman-nasa may be able to provide some context about performance to this discussion. I think someone said that there are areas of the GraphQL API that are limited by CMR performance, and could technically perform worse, and this library could abstract away the need for that knowledge, always doing what's most performant.

GraphQL's self-describing-ness is also huge. We could for example generate an API client: https://github.com/mirumee/ariadne-codegen
