Thomas Kolb 9dc1ab928c 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.

Thomas Kolb 6fc7e27c0b State tuning; safer startup
- Added some initial values for variables
- Prevent too fast state switching to bootstrap (only bootstrap 5
  seconds after state change)
- Made threshold voltage for switching from MPP to CV different from CV
  constant voltage
