To Discuss

I've taken this over from Mark since he is occupied with feature team work. I made the following changes since 5ae8e26

1. Instead of pushing the data in the mock data object, I made the object to provide an asyncstream that generate the mock data, to better simulate a real world usecase. Discussion at [New] Show device location with NMEA data sources #144 (comment)
2. I didn't touch the Task.detached part created by Mark. Initially I thought it would be better to use a task group for this purpose, but the tasks seem to work well, so I didn't change them other than making them private.

3. I didn't move the "status text" and their formatting methods to the view. While it is a better practice to only localize and format strings at the view level, it makes the code harder to read without adding too much benefit. My reasons were explained here: [New] Run valve isolation trace #203 (comment)
4. Please feel free to comment in the remaining open conversations.

Please also merge from the latest v.next. Here are some initial thoughts. After they are addressed, I'll add someone who's more familiar with async tasks to review.

I'd like to hear more feedback on the detached task part of code. See the unresolved conversations.

All other suggestions are applied.
