Granular control of pandas validation https://github.com/unionai-oss/pandera/pull/1490

There is now support for granular control of schema-level or data-level validations. This can be done via the `PANDERA_VALIDATION_DEPTH` environment variable. Schema-level (or metadata) validation includes things like column name checks and column data types, while data-level validation involves checks that operate on actual data values.


export PANDERA_VALIDATION_DEPTH= SCHEMA_AND_DATA check schema- and data-level checks (default)
export PANDERA_VALIDATION_DEPTH=SCHEMA_ONLY only do schema-level checks
export PANDERA_VALIDATION_DEPTH=DATA_ONLY only do data-level checks


Efficient Hypothesis strategies https://github.com/unionai-oss/pandera/pull/1503

Pandas data synthesis strategies now uses comparison operator functions for more efficient data synthesis. It also updates the minimum `hypothesis` version to `6.92.7`.
