Take Rawusage reset date into account when determining start date for sreport calls

[Comeani]

Currently, the start date provided to sreport is just the earliest start date across a group's active allocations. This is not necessarily accurate as the usage value being compared against the limits is the usage since the last raw usage reset.

This PR take the rawusage reset date into consideration, by returning the max of the earliest start date found and the most recent raw usage reset date. We want the max because start dates found prior to the raw usage reset date are what's creating the possibility of > 100% usage in the crc-usage output.

I tested this works properly on the cluster, and that it does not break crc-sus.

Minor styling note.

Our team tends to use the Google style guide, which is an extension of PEP8. The first line of docstring should fit on a single line. If you need to add extra details, add a white space followed by a longer multi-line clarification.

Thanks for the heads up, my bad for not just getting a quick review on this one. Is there an easy way to get pycharm to point this kind of thing out to me?

[djperrefort]

I don't think a review was necessary for something this small. I just happened to see it.

As for PyCharm, I have no idea. Maybe there's a plugin? I haven't checked.
