Feature Request: Delete range of tasks

**Is your feature request related to a problem? Please describe.**
If I have multiple tasks to delete and they were all created around the same time, it can become tiresome having to write lots of ids especially when they are sequential.

`tb -d 1 2 3 4 5`

**Describe the solution you'd like**
I would like to be able to type a command that can delete a range of tasks.

`tb -d 1-5`

It would also be good if one could specify multiple ranges together with single ids, for example:

`tb -d 1-5 7 9-11`

Thanks very much for this very useful tool!

Start with the CLI argument handling for the delete command and trace how task IDs are parsed. Verify the existing single-ID deletion behavior first, then use the examples in this issue as acceptance cases: ranges such as 1-5 and mixed ranges and IDs such as 1-5 7 9-11 should delete the intended tasks.
