Support for entity (wide colums) batch put/get

[afbarbaro]

Hi, thank you for this project! I have found it super helpful and really easy to follow the documentation. ⭐⭐⭐⭐⭐ rating.

I'm currently using WriteBatch to write many keys at once, which is necessary for having good performance on my bulk loads. I'm also using the multi-get (get with a list of keys). I now want to try using entities (aka "wide columns") but I don't see the equivalent batch write and multi-get operations. They exist in RocksDB, so any chance these could be exposed in RocksDict soon?

Again, thank you for this project!

Yeah right. Just like the current wide columns support, I'll need to first add an upstream PR to rocksdb to add C-API to support WriteBatch with entities.

I will probably work on it when I have time. This can be add to beta version relatively soon. But I'll have to wait for Meta to update rocksdb before releasing related features in non-beta versions, which can take much longer.

Try pip install rocksdict==0.3.24b3.
