Dump SQLModel

I have fixed a few bugs according to Copilot:

• Load and unload the data from Redis correctly (I forgot to put json.loads and json.dumps in some function )
• Pass attr_to_key to Serializer in Redis client
• Pass set_kwargs to set command
• Remove the requirement of id field in a model, used to create reference key, which is replaced with attr_to_key and key_factory.
• Add unloaded relationship to Deserializer (return None)
• Remove depth control in Deserializer
• And so more (look at the commit history below)

Atfer all, I think I need to sleep more because my brain is not braining now

I have fixed a few bugs related to Redis client. I also split the async function into separate class so it can run smoothly

I added attr_to_key as another way to modify the reference key

I wrote the Readme and created to pipeline for release

I added Redis support, now it will push and pull the data directly to the Redis

I added self_ref mode
In this mode, instead of storing reference in a separate place, now it will be stored in itself. This could help in managing obj but will increase the size of the output

The deserializer is done

I have completed the Serializer part.
It handle Relationship by using reference. If it is not mentioned before, stores it into an object, if so, reference to it :D
It also help deserialize object by storing object class so it can reconstruct the object
