* Update Metar.php
The reported pressure was always being assigned as hPa thus resulting display and conversion errors when the reported pressure was inHg.
Also the VFR/IFR (VMC/IMC) determination was using minimum 5 nmi and 3000 ft cloud base, it must be 5 km and 3000 ft.
With this state, this PR should fix issue #948 and partly fixes issue #963
