Make SimpleJSON optional

[baseplate-admin]

Is your feature request related to a problem? Please describe.
Hi there, It Seems that you guys bundle simplejson when installing the project. Is it possible not to do this? Because its yet another dependency when i have orjson, pysimdjson in my project.

Describe the solution you'd like
Make SimpleJson optional. Preferably with django-advanced-filters[simplejson]

Describe alternatives you've considered
Forking the project and making a downstream patch

Additional context
Now that CPython is getting faster chances are we wont need simplejson to make things faster unless i am missing something here

Thanks :D

I agree here. I even think simplejson should be removed since the features we need are included in stdlib.
