v0.2
this is the same functionality as v0.1
the idea was of v0.2 was to have one function per register
this makes the code more simple and doesn't require reading registers before writing into them
implemented are:
- setting up input channels (tested)
- changing to uni / bipolar mode (tested)
- changing data rates (tested)
- continuous conversion mode (tested)
- reading device ID (tested)
- getting current conversion channel (tested)
- getting conversion data (tested)
- single conversion mode, continuous read mode (not yet tested)
- changing clock mode (not yet tested)
- setting AC rejection filters on / off (not yet tested)
