Issue description

Quaternion::Quaternion(const Vector3 &p_euler); https://github.com/godotengine/godot-cpp/blob/master/src/variant/quaternion.cpp#L335

Does not properly implement all 6 conversion or let the developer choose the rotation order. https://github.com/godotengine/godot/blob/master/core/math/basis.cpp#L457

This function was purposely left out of Quaternion because the math for this would be duplicated. I would recommend converting from basis as a wrapper.

Steps to reproduce

Code review.
