Summary:
**Bugs:**
When following rocksdb_ivf demo to build executable file, its output as:
```bash
faiss/demos/rocksdb_ivf/RocksDBInvertedLists.h:52:35: error: 'faiss::InvertedListsIterator* faiss_rocksdb::RocksDBInvertedLists::get_iterator(size_t) const' marked 'override', but does not override
52 | faiss::InvertedListsIterator* get_iterator(size_t list_no) const override;
| ^~~~~~~~~~~~
make[2]: *** [CMakeFiles/demo_rocksdb_ivf.dir/build.make:90: CMakeFiles/demo_rocksdb_ivf.dir/RocksDBInvertedLists.cpp.o] Error 1
```
**Solution:**
Add relevant variable `void* inverted_list_contex` corresponding `get_iterator`'s base virtual function.

Storing Faiss inverted lists in RocksDB
Demo of storing the inverted lists of any IVF index in RocksDB or any similar key-value store which supports the prefix scan operation.
How to build
We use conda to create the build environment for simplicity. Only tested on Linux x86.
conda create -n rocksdb_ivf
conda activate rocksdb_ivf
conda install pytorch::faiss-cpu conda-forge::rocksdb cmake make gxx_linux-64 sysroot_linux-64
cd ~/faiss/demos/rocksdb_ivf
cmake -B build .
make -C build -j$(nproc)
Run the example
cd ~/faiss/demos/rocksdb_ivf/build
./rocksdb_ivf test_db
