+ Reformats `DataPackage.fetchMemberModels` method for better readability.
+ Ensures proper handling of `DataPackage.fetch` options in fetch method.
+ Improves error handling and logging for fetch operations.
+ Adds promise-based resolution for fetch operations to ensure proper flow control.
+ Ensures that the resource map is fully resolved.
+ Updates `DataPackage.fetch` documentation to provide examples.

Closes NCEAS#2607

* @property {boolean} fetchModels - If false, this fetch will not fetch
* each model in the collection. It will only get the resource map object.
* @property {boolean} fromIndex - If true, the collection will be fetched from Solr rather than
* fetching the system metadata of each model. Useful when you only need to retrieve limited information about
* each package member. Set query-specific parameters on the `solrResults` SolrResults set on this collection.
* @return {Promise} A promise that resolves when the fetch is complete
