Avoid hard-linked paths to model weights

[zietzm]

The evaluation script hardcodes the network paths on Thorshammer:

onsides/snakemake/onsides/evaluate/Snakefile

Lines 78 to 85 in efef3aa

	network_path = Path(
	"/data1/home/berkowitzj/onsides/models/microsoft/"
	"BiomedNLP-PubMedBERT-base-uncased-abstract"
	)
	model_path = Path(
	"/data1/home/berkowitzj/onsides/models/"
	"bestepoch-bydrug-PMB_14-ALL-125-all_222_24_25_1e-06_256_32.pth"
	)

This should be done differently, and these weights should be stored elsewhere.
