`pressure` is surface-level pressure not sea-level pressure

[cloneofghosts]

Describe the bug

I noticed the other day that the pressure values shown by Pirate Weather are much lower compared to other sites. It then dawned on me that Pirate Weather is using surface-level pressure instead of sea-level pressure which most other sites used.

I checked the Dark Sky documentation and it defines pressure as:

pressure The sea-level air pressure in millibars.

You've mentioned in the past that you want to try and keep things the same way that Dark Sky did things so this is definitely a bug.

Expected behavior

Pressure should be sea-level pressure

Actual behavior

Pressure is surface-level pressure
