Current Behavior
Within annotate_metadata_with_index, the index TSV is read without explicitly set dtypes. This can lead to numerical id strain values to be interpreted as numbers, leading to a ValueError when merging with the metadata.

Add test for annotating metadata with index with numeric strain names
861840f 
Adds a functional test to cover a use case described in #948.

@huddlej
Set dtype of strain column in sequence index
c49a5a6 
Sets the dtype of the strain column in the sequence index to "string"
prior to annotating metadata with that index. This change prevents
pandas from inferring the dtype as numeric when strain names are all
numeric.

Fixes #948
