**Release Notes**
The highligth of this release is a major refactor of `Daymet` to allow
for extending PET computation function for using methods other than
FAO-56.
New Features
- Refactor `Daymet` class by removing `pet_bycoords` and `pet_bygrid` methods and creating a new public function called `potential_et`. This function computes potential evapotranspiration (PET) and supports both gridded (`xarray.Dataset`) and single pixel (`pandas.DataFrame`) climate data. The long-term plan is to add support for methods other than FAO 56 for computing PET.
