Solutions

1. Handle the unexpected key in the error by extending the BLOOM.INFO parsing switch
2. Check the RedisBloom version for new info fields

When it happens

Trigger: Thrown at probabilistic.go:357 when the library encounters an invalid state.

Common situations: Tolerate unknown info keys by ignoring them rather than erroring, or pin module versions.
