Update Samples and Docs to match API changes

Addresses:

• #75
• #74

Match latest refinebio API changes

Refinebio changed some field names in the API. This updates the client to match that.

Catch all 500 server errors

This makes the client more robust to HTTP errors from the refine.bio API.

Handle non-JSON errors

If errors do not have a JSON body there will no longer be a JSONDecodeError thrown instead of a pyrefinebio exception.

Fix lazy loading

Fix lazy loading of OriginalFiles, DownloaderJobs, and ProcessorJobs.

Add downloadable_organism_names

Add the downloadable_organism_names property to the Experiment class.

Handle connection errors

This now raises a ServerError if we have a ConnectionError with the server.

Add missing argument to the `download_dataset` high-level function

This minor version bump adds the quant_sf_only argument to download_dataset, so that we can use this to download quant.sf files in our end-to-end tests.
