- uORB::SubscriptionBlocking is a specialized uORB::Subscription that allows you to do a blocking read
- this is intended to be an easy to use, hard to misuse replacement for the typical orb fd + poll pattern we've relied on historically
- landed, maybe_landed, or ground_contact required before the safety
button is able to disarm
- this reduces the risk of a faulty safety button triggering in regular
flight
- this is a new module for temperature compensation that consolidates the functionality previously handled in the sensors module (calculating runtime thermal corrections) and the events module (online thermal calibration)
- by collecting this functionality into a single module we can optionally disable it on systems where it's not used and save some flash (if disabled at build time) or memory (disabled at run time)

This should prevent debconf from asking questions during install.
Presumably, the exported env variable DEBIAN_FRONTEND is not taken into
account in a sudo command, hence we need to add it every time.
As far as I know these dependencies are only ever required when doing
analysis in ECL. At that point developers should be confident to add
what is required.
When having no velocity estimate the derivative was updated with zero.
When losing the velocity estimate this is fine since the resulting
derivative spike doesn't get used and acceleration is set to NAN.
But when regaining the velocity estimate the spike from zero to
the first estimated velocity gets used as acceleration in the position
controller and results in a twitch.
To solve this I use the derivative reset I introduced in pr #13522
