I would absolutely love to be able to query this month's budget for a given category. For example, being able to ask the API for my "Food" budget for the month and have a response that details what my budget _is_ for the month, and what I've spent against that budget for the month. Basically I want the data available here: https://my.lunchmoney.app/budget/2021/01?category=138420 via the API!
