`geopressure_check()`

[Rafnuss]

Quick initial check

• [x] Stationary period duration: warning below 6 hours, danger below 2 hours
• [x] Flight duration: warning below 2hours, danger below 1 hours?
• [x] Pressure values: within possible range?,
• [x] Pressure values: sufficient for each stationary period.
• [x] Pressure check abrupt change in pressure during stationary period?
• [x] Pressure check smooth/outliar? Assuming that abrupt change is sufficient

Relying on geopressure_timeseries

• [x] no pressure outliar (assuming std dev)
• [x] ...

Return suggestions

• [ ] check elev_id to be the same
• [ ] combine stationary period which are too similar
• [ ] ...
