feat: task table widget (#7470)
### Description
Implementation of the "task table" component of our new UI. The table is
comprised of the task names and the task status which displays an ASCII
representation of when a task started and finished.
### Testing Instructions
Added some unit testing for stateful parts of task table and the task
duration rendering. I held off on the unit testing of the task table
rendering as I expect us to change styling a bit.
Added example binary that fakes some task execution, this if meant to
take place of unit test for rendering. Please play around with it!
