Update VolumeDataRegion code to match commercial VDS including logic to skip duplicated voxels in LOD chunks.

Change rules for LOD voxel rounding so min and max are not rounded separately (i.e. all voxels covering the requested area) but instead gets a consistent number of voxels independent of how the min is rounded.

- allow customizing scopes
- properly add Content-Length header in refresh HTTP request (avoid 400 responses with some IDP eg Azure)
- make clientSecret optional, as it is not needed when using PKCE

It does not support downloading the package any more without building
all the dependencies manually. We are cloning git tags for now.

This makes uri handling in SEGYImport easier and makes it possible for
SEGYImport to read seagy from dms location. This is a behavior change in
the IOManager api so all backends have been manually verified

We can not enable the performance fix because of another bug in the AWS
backend, but we now detect zero size blobs by a sideeffect of reading
head.
