Add altitude above sea level to Get Location v2

Currently, Get Location V2 returns the GPS altitude above the WGS84 ellipsoid. Whilst useful for some things, it's not a very human-relevant number, as most people think of altitude in terms of the height above sea level. Here's a good thread explaining the issue. Correcting for this issue within Tasker is non-trivial. 

Android now has built-in support for making this correction. Could we have optional access to it through Get Location v2, please?
