Aalekh Patel 4e6b6f8a12 Add the ability to clone and read binary indexes to the C API. (#3318)
Summary:
I noticed we have a pretty decent C API for binary indexes and please correct me if I'm wrong but we seem to be missing a couple of functions, like the ability to clone and read binary indexes. This PR provides those functions.
