Cheap Ruler Versions Save

Minor fixes to the list of published files for v3.

• Breaking: changed the API from cheapRuler(...) to new CheapRuler(...) (more idiomatic for ES).

• Added pointToSegmentDistance(p, a, b) method.
• Fixed all methods to work across the date line.
• Breaking: switched from FCC formulas (based on Clarke ellipsoid) to a more modern WGS84 Ellipsoid model of the Earth, so the values calculated may change slightly.

• Fixed and documented pointOnLine t result property #30
• Added default export for use with ES modules setups
• Added minified build to the package
• Added offset method to TypeScript typings

• Added ruler.offset(point, dx, dy) method.

• Improved error handling for invalid units.

Made all methods much more precise by using an FCC-approved formula for ellipsoidal Earth projection. #13

• Added ruler.lineSlice
