[x] Add effective_date attribute to groundwater well dimension data.
[x] Improve consideration of well replacement dates. Create a well replacement list with well_id and date, possibly new well height and depth. Need to use the appropriate well height for each well measurement. See TODO in Ground_to_Water.py -> calculate_groundwater_level() function.

[ ] Improve water meter offset. Right now hard-coded to 3cm. Examine range of meter_offset, did I consistently measure from the top or bottom of the sensor?! Re-test the meters if possible.
[ ] Add ground_to_water_greater_than_cm attribute to groundwater_data where "no water" found.
