VTOLs consume a lot more power in hover copared to fixed-wing fligt.
The remaining flight time thus should reset if one switches from MC to FW,
as otherwise it takes several minutes until the estimate goes down.
The argparse module has been builtin to Python since
Python 3.2, released in 2011 (see
https://docs.python.org/3/whatsnew/3.2.html). Further,
the argparse pip module has not been released or updated
since 2015, and lacks some of the features of the modern,
built-in argparse. Drop the pip installed version in
favor of the built-in version.

fix: ControlAllocator float and int comparison bug
There was an incorrect comparison between a float variable `dt` and a `uint64_t` value representing 5 milliseconds (`5_ms`). As a result, `do_update` could never become true even if the last torque setpoint was received more than 5 milliseconds before.
To solve this, the `5_ms` value has been converted to seconds (0.005f) for the comparison with `dt`.
In this mode, the mag is used to inilialize the heading.
During flight, the heading is predicted using gyros and corrected
by GNSS measurements if available.
Previously, if a mag was not required (not index 0 and not used by ekf),
it was not counted in num_enabled_and_valid_calibration.
If a user set SYS_HAS_MAG to e.g. 3, it would then trigger a preflight
failure, even if there were 3 calibrated and enabled mags.
The EKF can recover from an initial bad earth mag field estimate.
Constraining the field is not necessary and can lead to an unpredicted
behavior of the filter.
Declination fusion is safe to run even when the horizontal field is 0
On slowly moving vehicles (e.g.: boats, rovers), the yaw estimator has
worse convergence than the main EKF. Resetting the mag states using the
yaw estimator as reference can lead to poor heading. Also, the EKF can
recover really well from initially incorrect mag states.
The previous default of 900m leads to many warnings if left
unchanged, especially if the vehicle is already in-air when
the Mission is started.
