Adapt Huggingface predictor to PubMed

[pjuangph]

Part 1 David Tasks:

1. write a downloader
2. write an xml to panda file reader

Part 2 Paht Tasks:

1. Adapt the petal-labeller with scibert to predicting the mesh terms labels. Predicting multiple labels may be tricky but should be investigated.

Paht and David Tasks. Alex too, why not.

1. Look up machine learning models that can do multiple classifications in NLP or images. Something we could use to classify multiple meshterms.

Purpose of this task is to use more data and from that decide if Bert is the best way to go and if we need to improve Bert, how accurate can we make the prediction? The dataset will be more than what we currently have and this is a great benchmark for predicting the Labels from Colleen and Alex
