Add proper error messages to linter; fix bug in 'collinear-segments' rule (#5061)
* Implement better linter error handling; fix error in 'collinear-segments' lint rule * Revert changes * Fix error with resolution tips * Fix lint error * Fix minor errors * Increase performance bumping svg-path-segments version * Minor change in function name and bump svg-path-segments to 0.1.5 * Update function doc * Remove 'segmentsSVGPath' function and update functions documentation * Fix error in index number * Fix automatic collinear segment
