Split the functionality into child classes to make it more explicit where the data is sourced from at the call site. Added the functionality to source data from a URL directly. Note that the data is cached in a temporary file as controlled by the earthkit data cache policy setting. This is becase stream source does not implement the sel method at this time.

Code changes:
data_source.DataSource is now an abstract base class
Refactored FDBDataSource, FileDataSource, PolytopeDataSource that inherit from DataSource
