Sensitivity mapping for 4x is wrong

[beeka]

The delta_sense bit mapping dictionary looks like this:
SENSITIVITY = {128: 0b000, 64:0b001, 32:0b010, 16:0b011, 8:0b100, 4:0b100, 2:0b110, 1:0b111}

Note that the values for 8 and 4 are the same. The CAP1188 datasheet says that 4 should be 0b101.

Ooof! I'll get this corrected when I can.

I found this while adding get/set sensitivity functions. I've added my patches, in case they are useful. add_sensitivity_fns.txt
fix_mapping.txt

Added these as part of #23 - thank you!

Hey I'm only- but not quite- four years late!
