Description

Since there doesn't seem to be a mention of the reverse_string_indexer in mleap/python/mleap/sklearn/preprocessing/, I don't believe the ReverseStringIndexer is currently supported for sklearn.

Contributor guide

Examine existing sklearn indexer implementations in mleap to understand the pattern, then implement ReverseStringIndexer following the same structure.
