New approach to MPP tracking
...
Test multiple points for PWM, switch to the one which gives the most
power, repeat. If two consecutive tests give the same point, hold that
for some time or until power changes too much.

- Prevent too fast state switching to bootstrap (only bootstrap 5
seconds after state change)
