RasPi 4 + Grove TDS sensor code (No module named grove.adc)

Hi @elenfoxx
I had the same problem with you today, which prompted ModuleNotFoundError: No module named ‘grove.i2c’.
The reason is after I use “git clone https://github.com/Seeed-Studio/grove.py” to clone the grovepy, I forget to use

# Python2
sudo pip install .
# Python3
sudo pip3 install .
