[Feature request] Create new / repurpose NCalc / JS function driverrelativegaptoplayercombined.

[derrickmoeller]

Is your feature request related to a problem? Please describe. The driverrelativegaptoplayercombined function is poorly named, it actually returns the overall gap to player (laps or gap).

Describe the solution you'd like Rename driverrelativegaptoplayercombined to drivergaptoplayercombined, this would align with existing functions drivergaptoleadercombined and drivergaptoclassleadercombined.

Repurpose driverrelativegaptoplayercombined to return a formatted string version of driverrelativegaptoplayer e.g. (+3.77, -0.46, +9.98, etc).
