v0.45.0

Special thanks to Albert Teoh for contributing to this release.

This release contains a large number of breaking changes, primarily surrounding geometry validation. See #525 for background and an overview of the changes.

• Breaking change: The geom.ConstructorOption type has been removed. Previous uses of geom.DisableAllValidations can be replaced with geom.NoValidate. Previous uses of OmitInvalid should be managed manually (no replacement for this functionality is provided).

• A Validate() error method is added to Geometry and each concrete geometry type. This allows geometry constraints to be checked after geometry construction.

• Breaking change: Geometry results from GEOS (wrapped by the github.com/peterstace/simplefeatures/geos package) are no longer validated. The variadic constructor options in function signatures have been removed. If users wish to validate these results, then Validate() can be called manually.

• Breaking change: The TransformXY methods no longer validate geometry constraints of the result. The variadic constructor options have been removed as method parameters, as have the error returns. If users wish to validate these results, then Validate() can be called manually.

• Breaking change: The direct geometry constructors (NewPoint, NewLineString, NewPolygon, NewMultiPoint, NewMultiLineString, NewPolygon, and NewGeometryCollectiion) no longer perform any geometry validation. They no longer accept constructor options or return an error, resulting in a function signature change. If users wish to validate the results, then Validate() can be called manually.

• Breaking change: XY's AsPoint method no longer checks the validity of the result and no longer returns an error. An AsPoint method is added to the Coordinates type to shadow XY's AsPoint method (since XY is embedded in Coordinates).
