Calculated key is short a nibble

[allotria]

I used the flipper zero together with the mobile companion app to calculate the keys for my front door lock.

The calculation went smoothly according to the app but the calculated keys seem to be short a nibble.

The result was i.e. DAB1C1EBF8C and gets ignored by the flipper in user dict.

Flipper firmware: XFW-0040
companion app version: 1.4.1

@allotria the code for the Flipper companion app is actually over here https://github.com/flipperdevices/Flipper-iOS-App and the mfkey32v2 part seems to not be maintained by the original author.

long story short, I created a PR to fix this, as I stumbled over the same flipperdevices/Flipper-iOS-App#181
