redis option for json serializer

[devvit]

To use json instead of pickle for serialize, you' d better set a redis instance like this:

from flask_session import Session, RedisSessionInterface

RedisSessionInterface.serializer = json
rds = redis.Redis(decode_responses=True) # make sure utf8
app.config['SESSION_REDIS'] = rds

Msgspec will be added in 0.7.0 with JSON and Msgpack support. Also note, subclassing interfaces will need to import redis.RedisSessionInterface.

This is a great tip to use for best security until Pickle is fully removed in 1.0.0
