Bitmask #159
Description
It would be nice if we could have a bitmask option next to the values option. For simplest implementation it can be made the same, except each value is shifted with the position in the array. This could make it easier to understand messages values like INS_EKF2: control_mode if the messages.ml can parse it.
I'm not 100% sure how to implement this correctly in the paparazzi project messages.ml that is why I made this issue.
