Pygridmet

-------------------

New Features
~~~~~~~~~~~~
- Add a new function called ``get_conus`` for downloading the daily
meteorological data for the entire contiguous United States (CONUS) from
the GridMet service, for given years and variables. This can be accessed
from the CLI using, for example, ``pygridmet conus -y 2010 -v tmmn`` command.

Breaking Changes
~~~~~~~~~~~~~~~~
- Drop support for Python 3.8 since its end-of-life date is October 2024.
- Remove all exceptions from the main module and raise them from the
``exceptions`` module. This is to declutter the public API and make
it easier to maintain.

-------------------

Internal Changes
~~~~~~~~~~~~~~~~
- A release without change to match the version of other HyRiver packages.

-------------------

Internal Changes
~~~~~~~~~~~~~~~~
- Add the ``exceptions`` module to the high-level API to declutter
the main module. In the future, all exceptions will be raised from
this module and not from the main module. For now, the exceptions
are raised from both modules for backward compatibility.
- Switch to using the ``src`` layout instead of the ``flat`` layout
for the package structure. This is to make the package more
maintainable and to avoid any potential conflicts with other
packages.
- Add artifact attestations to the release workflow.

-------------------

- Initial release on PyPI.
