Closes #256.

As per #256, i changed the rglob pattern search to glob and added a possibility to specify --tasks-pattern option multiple times.

Actually I like the approach, because it will make it task searching more flexible. I will update minor version because of this PR, Since it might break apps that were using custom --tasks-pattern.

I still have to make some corrections in import_tasks and I'd also like to write a test for it. I'll drop the draft status when the PR is ready :-).

Also, can you make import_tasks to accept either sequence or string as pattern? Because I was using this function in some taskiq-related third-party libs.

Sure, done :-). I added some tests and believe that the PR is ready for review.
