Commit Message

Skip unset sample metadata fields in load_sample (closes #5) (#6)

When a sample sheet doesn't supply antigen / MHC fields, load_sample was
unconditionally assigning sample.<field> to adata.obs, producing
all-None object-dtype columns. Concat across samples kept them, and
anndata.write_h5ad then choked categorizing them ("Can't implicitly
convert non-string objects to strings"), the same shape of failure as
the has_TRA bug fixed in #4.

Skip the assignment when the value is None — downstream readers
already guard with `if col in adata.obs.columns`.

Adds a regression test that loads a sample with no antigen metadata
and round-trips through write_h5ad.

Bumps version to 0.2.8.
