remove dependency on detectron2 #115
Description
Hi,
I'm a researcher trying to use the BiomedParse model. I have some of my own libraries which I would like to use in conjunction with BiomedParse, for e.g. data loading.
BiomedParse's dependency on detectron2 (a package that has not been updated for about 5 years now) makes it quite hard to resolve dependency issues with other packages. The dependency does not seem to be very strong, only for some layer types and norms. As such, it should be feasible to remove the dependency on detectron2, making installation much simpler.
