ValueError in battery sizing functions causes errors for batch jobs

[brtietz]

The dGen team reported that they were commenting out the following lines in their local PySAM implementations in order to make their code run successfully: https://github.com/NREL/pysam/blob/a7dc841caa011dbccd0f998e390ec865b556cb2a/files/BatteryTools.py#L306

While that line makes sense for a single resizing, we should consider the implications for batch jobs. Decide whether to:

1. Maintain the error as is, but add try-except to our examples (with recommendations of how to handle the except_
2. Increase the tolerance
3. Provide a user-specified tolerance or allow users to turn the error off in the function call.

I tried (1) today and it didn't have the hoped for results in dGen - code outside of the relevant function needs to access battery output variables, so it would end up being a larger refactor. I'm leaning (3) and putting this on the SAM meeting agenda to discuss.
