Added new float state; Some fixes
...
Typical charge cycle: MPPT until 14.4V, then switch to CV and hold
14.4V. After 2 hours switch to float charging at 13.8V.

Read out the stm32 temperature sensor
...
The value is output using
1. the LCD
2. the UART
The CPU load calculation has been removed/commented out, as it is no
longer used.

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)
