Consider WRF downscaled outputs for historical / inventory drivers

[dlebauer]

• CalAdapt historical downscaled met doesn't appear to update regularly.
• The producer has downscaled met data available here: https://cadcat.s3.amazonaws.com/index.html#wrf/ucla/
• Evaluate whether it is viable to replace our current historical met data sources with this data source
• If so, create one or more new issue(s) to track implementation
