We should clarify in the documentation how to load in AIRR Rearrangement and Change-O files. Maybe a very brief vignette that shows that you should use
airr::write_rearrangement for AIRR data and
alakazam::writeChangeoDb? These functions both deal with TSVs, but they have different behaviors for
NA values and case conversion of sequences that are specific to each format.
