improvement: nested filtering

[denverbaumgartner]

we currently lack nested filtering throughout the repo, it would be great to add this in for obvious use cases, for example on the AidData class allowing to filter get_aid_history by token would be 💯

i know this is supported in subgrounds, need to go dig around more and find an example or see whats going on underneath so i can utilize the proper syntax. this would be a good place to add in an example to that repo to help out others who are experiencing the same problem 🫂
