gui: Add new form for temp adc filter cfg and settable polling rate

List of Changes:
1. Get report via polling instead of active report mode
2. Allow user to set a custom report polling rate while settings polling rate is fixed to 10Hz
- it is necessary for pid autotune to function correctly
3. Add a form for configuring temperature adc filter
4. Use two different timer for polling report and settings to optimize performance

Known Issue:
1. CPU utilization increases with the report polling rate as for each report recv-ed, gui renders and plots one frame of the 4 graphs
