Version 0.3.5 - 2022-06-05

The 0.3.5 release mainly addresses the scaling issue in GPU viewshed to gain better accurate triangulation.
The GPU raytraced viewshed should now give comparable results to the CPU version.
However, the 2 versions use 2 different approaches, there can be slightly differences at some points
where a version returns visible while the other considers them as invisible.
Many thanks to @nodell111, @a7az0th, and the maintainers @thuydotm for contributing to this release.
