Refactor
- Make all parameter levels equal for all weather services to reduce complexity in code
- Change `tidy` option to `shape`, where `shape="long"` equals `tidy=True` and `shape="wide"` equals `tidy=False`

Refactor
- Naming things: All things "Scalar" are now called "Timeseries", with settings prefix `ts_`

- Geo: Change function signatures to use latlon tuple instead of latitude and longitude
- Geo: Enable querying station id instead of latlon within interpolate and summarize
- Geo: Allow using values of nearby stations instead of interpolated values

Fix
- Fix timezone related problems when creating full date range

Feature
- UI: Add interpolate/summarize methods as subspaces
