Mixed types arrays in ankiconnect

[uieoa]

First of all, thank you for a great work with this plugin

Some methods like getNumCardsReviewedByDay do return an array with various data types, like this:

{"result": [["2023-10-21", 10], ["2023-10-18", 45]], "error": null}

where "2023-10-21" is a string and 10 is int.
I think it makes no problem for python or js but for swift and other strong-typed languages this behavior causes a lot of troubles.
Hacks are really dirty: https://stackoverflow.com/questions/48996643/parse-json-array-that-contains-string-and-int-in-swift-4

I would like to suggest two solutions:

1. New methods like getNumCardsReviewedByDay_strong which will always return an array of array of strings like:
   {"result": [["2023-10-21", "10"], ["2023-10-18", " 45"]], "error": null}
2. New methods like getNumCardsReviewedByDay_strong which will always return an array of some data like:
   {"result": [{"date": "2000-01-01T01:01:01", count: 10}, {"date": "2020-02-02T01:01:01", count: 45}], "error": null}

I think I can make a PR to any of this but which way do you like the best?

Kind regards
