This implementation is a baseline implementation and makes no attempt to be tamper-proof. A monotonic counter like the W25R64FV or a similar HW facility would be required to achieve this.
- constructor initalization fix
- set trigger time for ground contact hysteresis
- updated ground_contact_state logic
MulticopterLandDetector:
- added hysteresis for ground_contact
VtolLandDetector:
- get_ground_contact_state function that return the one form MultcopterLandDetector
FixedWingLandDetector:
- get_ground_contact_state with a return false: requires implementation
This allows to detect ground contact before concluding the system is landed. This allows to disable some parts of the horizontal control system and only control the vertical position to avoid tipping over.

The existing orb_advert_t use thoughout the code sometimes tries
to treat it as a file descriptor and there are checks for < 0
and ::close calls on orb_advert_t types which is an invalid use
of an object pointer, which is what orb_advert_t really is.
Initially I had changed the -1 initializations to 0 but it was
suggested that this should be nullptr. That was a good recommendation
but the definition of orb_advert_t had to change to void * because
you cannot initialize a uintptr_t as nullptr.
