## Motivation
The timings in the batch generator are a little optimistic; a minor
change is needed to make them more correct.
## Changes
Include the time spent in the API in the generation tps and make sure to
send all requests simultaneously
## Motivation
Batching will require us to send tasks concurrently and queue them up.
Our current infrastructure cannot handle that all. This PR gets us
closer to this by allowing multiple tasks to be sent in parallel and
then queuing up tasks.
## Changes
Change Plan logic
Make runner main into a class
Add a "BatchGenerator" to which tasks can be submitted (although tasks
are handled sequentially) and sent back through an MpSender.
Refactor runner to accept tasks during generation
Keep the generator threading
Separate the runner into several files for better readability
## Test Plan
### Manual Testing
Tested manually, needs a lot more automated testing. Cancellation still
works on a single device. Needs checking on multiple devices.
### Automated Testing
