Update abi_l2_nc to include filename metadata similar to abi_l1b

[djhoese]

This PR makes the abi_l2_nc reader more consistent with the abi_l1b reader. My use case is that I want to format my output filenames (from Scene.save_datasets) similarly for all ABI data. Right now that includes some of the information about the sector and a few other parameters in the filename. Not all of this information was available, but has been added in this PR.

CC @yufeizhu600. If you could please review these changes it would be greatly appreciated.
