[FEATURE REQUEST] Execution of a dependent tasks

[tony-spark]

Is your feature request related to a problem? Please describe. I want to run tasks which may be dependent on each another: I want to schedule tasks in one batch, but its' execution goes according to dependencies between tasks

Describe the solution you'd like I want option to tell asynq that one task depends on anothers.

Describe alternatives you've considered I suppose this could be achieved by writing my own task scheduler on top of asynq (but I prefer it to be core feature)

Additional context Maybe there's already the elegant solution with current functionality of asynq
