Add more epitope databases to datasets

[grst]

List adapted from #54.

• The MAIT reference database with invariant CDR3
• huARdb https://academic.oup.com/nar/advance-article/doi/10.1093/nar/gkab857/6381136?rss=1
• McPAS-TCR
• PIRD
• The Adaptive Biotechnology database, used to identify (and exclude) public clonotypes shared between unrelated individuals (Dean et al., 2015)
• There might be quite some SARS-COV-2 TCR-epitope resources as well (e.g., Grifoni et al. 2021)
• VDJDB
• IEDB

@ausserh, how about adding your code for IEDB to scirpy directly?

More databases can potentially be accessed via biocypher. See also #404.

Here's a preprint where they compiled a unified database: https://www.biorxiv.org/content/10.1101/2024.10.26.620398v1
Maybe also a good starting point for the knowledge graph.
