gyro sensitivity

there have been complaints about not being able to set gyro sensitivity high enough, this is *not* something that should be addressed on the LUS side, as it's actually an issue in SoH with multiplying by an arbitrary magic number (`750.0f`).

i think to resolve this we should:
* `#define` the value
* play around with a few different values, see what feels reasonable (probably get feedback from people who have complained)
* make sure we have a good range of sensitivities when setting it in the menu (0% - 100%)
* make sure we have a good default sensitivity percent in the menu
