feature request: access "study prefix" in python

[comorbidity]

pyproject.toml contains a pointer of which files to include
this is implicitly the "study prefix"

would be nice to say "from my_study_name import study_prefix" or equivlant

priority: low feature request

so with the toml package (which we are installing with the core library), you can get to this as follows:

import toml
data = toml.load('./path/to/manifest.toml')
print(data['study_prefix'])

We can look into building this into templates/helper functions as we harden them for inclusion in the core library, but I think if you're writing custom generators inside of study directories, we're not being implicit about the way users are doing that, so it's a little bit trickier - it would more likely look something like from cumulus_library.helpers import get_study_prefix or something like this.

If you're ok with this, I'd like to close this issue here and move it to the core library.

(we could, alternatively, maintain a file in this template to accomplish the same thing, but I think putting it in core would be less of a maintenance headache here).

Yes @dogversioning thats perfect
from cumulus_library.helpers import get_study_prefix
