setupFrustum bug

[ShihanWang]

in open_chisel/src/camera/PinholeCamera.cpp function: void PinholeCamera::SetupFrustum(const Transform& view, Frustum* frustum) const, line 2 where Frustum::SetFromParams(xxx) was used, but the 4th param should not be intrinsics.GetFx() ?
the code is :
void PinholeCamera::SetupFrustum(const Transform& view, Frustum* frustum) const
{
assert(frustum != nullptr);
frustum->SetFromParams(view, nearPlane, farPlane, intrinsics.GetFy(), intrinsics.GetFy(), intrinsics.GetCx(), intrinsics.GetCy(), width, height);
}
