Search arg in List tasks API - more than one state

[YagoMaia]

Hello, I was using the Flower API filtering tasks by their states, which was not meeting my needs, when I encountered a dilemma. I wanted to know if it would be possible to implement, or if it has already been implemented, how I would go about filtering the /api/tasks endpoint by passing more than one task state as an argument.

Example: I would like to filter all tasks that have the PENDING and FAILED states at the same time, is it possible to do that?
