Significant internal refactoring to improve schema generalizability, harmonize behavior between the python and R libraries, and prepare for AIRR Standards v2.0.

Rearrangement:

• Added the aux_types argument to read_tabular, read_rearrangement, and read_alignment to allow explicit declaration of the type for fields that are not defined in the schema.
• Renamed read_airr, write_airr, and validate_airr to read_tabular, validate_tabular, and validate_tabular, respectively.

Data Model and Schema:

• Defined new read_airr, write_airr, and validate_airr functions that support AIRR Data Model files that store arrays of objects in JSON or YAML.
• Added support for the AIRR Model Data File and associated schema (DataFile, Info). The Data File data format holds AIRR object of multiple types and is backwards compatible with Repertoire metadata.
