The line chart for the odometer is ready.

What it Does

Closes #353
It added line chart to the odometerview. I added a few more instances of odometer readings into the preview, so that it shows better in the previewer.

How I Tested

After entering a new odometer reading the chart is displayed above the list. I was not able to test it all the way that I wanted because the firebase emulator wasn't working properly for me. Even though I tried restarting everything and I ran the emulator from within the backend and it started up properly in the terminal, however, when I tried running simulator it got this error.

11.4.0 - [FirebaseFirestore][I-FST000001] WatchStream (80b17503) Stream error: 'Unknown: An internal error has occurred, print and inspect the error details for more information.'

Notes

• Anything else that should be noted about how you implemented this feature?

Interactive chart would be a good next step perhaps. It was in WWDC23 video here. https://developer.apple.com/videos/play/wwdc2023/10037/

Screenshot

• Add a screenshot of your new feature! OR show a screen recording of it in action. (On the simulator press Cmd + R to record, and the stop button when done). This video should be no longer than 30 seconds.
