Limor Fried b521dd370d Add register control functions for charge/input limits and system voltage 
- Add setChargeCurrentLimitA() and getChargeCurrentLimitA() functions
  * Range: 0.04A-2.0A in 0.04A steps (register 0x02, bits 10:5)
- Add setChargeVoltageLimitV() and getChargeVoltageLimitV() functions
  * Range: 3.5V-4.8V in 0.01V steps (register 0x04, bits 11:3)
- Add setInputCurrentLimitA() and getInputCurrentLimitA() functions
  * Range: 0.1A-3.2A in 0.02A steps (register 0x06, 8 bits shifted by 4)
- Add setInputVoltageLimitV() and getInputVoltageLimitV() functions
  * Range: 3.8V-16.8V in 0.04V steps (register 0x08, 9 bits shifted by 5)
- Add setMinimalSystemVoltageV() and getMinimalSystemVoltageV() functions
  * Range: 2.56V-3.84V in 0.08V steps (register 0x0E, 6 bits shifted by 6)
- Update test example with all register functions and F() strings for SRAM optimization
- All functions verified working with hardware showing correct default values
