`decorator` not included in `pyproject.toml`

[JackReevesEyre-NOAA]

Installing thalassa with pip, which (I think) uses the pyproject.toml file for dependencies, results in import errors. Specifically these are related to the decorator library not being included in the env.

To recreate:
In a bash shell:

mkdir thalassa_test_env
cd thalassa_test_env
python -m venv .venv
source .venv/bin/activate
pip install thalassa
python -c "import thalassa"

results in:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/jre/test/thalassa_env/.venv/lib/python3.12/site-packages/thalassa/__init__.py", line 9, in <module>

Hmm... weird, probably some other dependency used to pull decorator and in recent versions dropped it or something. Anyway, doing a pip install decorator before should resolve it for the short term. I will try to make a new release in the following days.

Thanks @pmav99 - that works, and I also added it to the requirements in the package I'm using thalassa in.
