Allow member_id to be optional

[mgrover1]

While working on a catalog with Dan Marsh, I ran into the following case b.e21.BWma1850.f09_g17.release-cesm2.1.3.c20200918 where the last part after g17. would be the member id, but cannot be split with the typical . separator. For now, I added a try except block where if it has an issue with the member id, it inserts None.

I'm curious... Does CESM have a naming convention for member_id? If so, could we replace info['member_id'] = int(info['case'].split('.')[-1]) with a more flexible, robust version?

I think this is the problem Dan mentioned... perhaps removing the requirement that the member_id be an integer would be a better fix.

@mgrover1, 👍🏽 Could you run this on Dan's notebook to confirm that this works?

@andersy005 I tested on this Dan's files, and it works. We need to make sure we are using the parse_cesm_history parser here too since technically these are history files (multiple variables), with a special case where there are multiple times as well (365 for each file)

Thank you, @mgrover1
