indexer: use a byte array for checksum The index's checksum is not an object ID, so we should not use the `git_oid` type. Use a byte array for checksum calculation and storage. Deprecate the `git_indexer_hash` function. Callers should use the new `git_indexer_name` function which provides a unique packfile name.
