hopeful to add support for orjson to speed up event json passing

[sonicgemini]

otherwise need to add monkey patch, like (copy from google advice and tested it worked)

# in engine.py file
import orjson  # add this
import json
import copy
import durable_rules_engine

from . import logger

# 1. Define a wrapper because orjson returns bytes, but durable-rules needs strings
def orjson_dumps_wrapper(obj, **kwargs):
    # Durable-rules may pass arguments like 'ensure_ascii' which orjson doesn't use
    return orjson.dumps(obj).decode('utf-8')

def orjson_loads_wrapper(s, **kwargs):
    return orjson.loads(s)

# 2. Monkey-patch the standard json module used by durable-rules
# This must be done BEFORE importing or using durable-rules functions
json.dumps = orjson_dumps_wrapper
json.loads = orjson_loads_wrapper

def _unix_now():
    dt = datetime.datetime.now()
.......

is is possible to add an engine support to couple the json dependency by adding injection setting.
