New SurveyParameters class

[jonnymaserati]

Rather than rely on your directional driller for survey parameters in your header or for converting between WGS84 and map projections, there's a SurveyParameters class in the survey module for doing it.

Also added to the utils is a function for calculating annular hole volumes, very useful when used with utils.ureg for easy unit conversions.

Small changes and bug fixes, so nothing should break.
