Run metadata_to_api on just one dataset

[chrowe]

Run contents/src/init.py` interactively instead of following the readme.

Add metadata_to_api = metadata_to_api.loc[metadata_to_api['New WRI_ID']=='{ID of the dataset you want to update}'] replacing {ID of the dataset you want to update} with an actual ID.

For Example metadata_to_api = metadata_to_api.loc[metadata_to_api['New WRI_ID']=='com.039.rw0']

I also like to add metadata_to_api.head() after that just be able to preview the output to make sure it is the datasets I was expecting.

add main() at the bottom if you want to be able to run it all at once.
