MIDI-Mapper: Require controls to be actuated/moved twice before mapping signal in order to detect whether value has 14, 7 or 1 significant bits.
Also, support non-motirzed faders/endless encoders by not transmitting control change until value of controller comes within 5% of value of signal. Also, change file format (backwards compatible). Also, fix some issues with NRPN decoding.pull/119/merge
