Proposal for varios changes

[helicocrasher]

Hi @Tjoms99

So as propsed lets try a pull request. It is the first one I ever tried, so you might need to be patient.

Main Changes:

• Setting of the BQ25101 Chip. On function to set the charge current (100 mA 50mA or 0 mA)
• elimination of the enable routines as they do no really work with the BQ25101 - instead status read out wheter charging is active is equal to the chargeLED.
• Voltage read during charging switches to 0mA to be able to read battery voltage .. and after reading restores the previousls se charge current.
• LED blinking blue green red off just for the fun of it.

Please check which parts you might like.

Cheers

Good stuff @helicocrasher! Will test the code later, left some comments here for you to think about:) The LEDS are a cool feature but I think we should use it in another way. Maybe we could show the battery status with some charging animation as they do for electric vehicles (is the battery charging, is it charging and at full capacity?); For now, I think we should remove the LEDS. There are some stuff we need to think about here before adding it (user might already be using the LEDS), I can open a new ticket for this:)

Great work.
