This PR changes index_netcdf to support indexing time-invariant netCDF files. These datasets contain information that doesn't generally change over time, like elevation or soil type. Datasets without a time dimension simply omit the TimeSet attribute when indexing.
Nchelpers is updated to version 5.5.3, which adds the is_time_invariant attribute to CFDataset and handles generating unique_ids for time-invariant datatsets.
