Consistent rounding of LOD voxels when computing overlap so we never copy the same voxel twice. Fixed some bugs with FullResolutionDimension handling. Made code follow naming conventions for local variables.

Added GetVolumeSubsetBufferSize() API to calculate required size of a buffer for a call to RequestVolumeSubset.

Added GetLODSize() function that gets the number of voxels at a particular LOD from a voxel range. This needs to be part of the public API to make sure everyone knows how the rounding is done and can do it consistently.

Use AccessManager as the short name of the VolumeDataAccessManager to be consistent with using AxisDescriptor as the short name of VolumeDataAxisDescriptor, Layout as the short name of VolumeDataLayout etc. Added documentation for GetLayout() and GetAccessManager() functions.

and add functionality for adding noice to data pages. Also add a test
for the InMemory IOManager that uses the nocie functionality

- Set CMAKE_INSTALL_DIR to lib${LIBSUFFIX} for Azure Storage SDK
  * Azure Storage SDK does not use GNUInstallDir cmake include to
    set the CMAKE_INSTALL_<dir> variables resulting in invalid LIBDIR
    paths for distributions that use lib64. However, they provide a way
    to override it which is what this change uses to set the correct path

- Add WERROR=OFF for cpprestsdk
  * Warning about deprecated-copy when building with gcc 9. Causes
    the build to fail if werror is enabled

- Remove const from dimensionDistribution
  * uniform_real_distribution<float> call operator is not const which
    causes an error when building with gcc 9

Moved ValueConversion.h and VolumeSampler.h to the public API. Fixed includes and list of headers to install.

Added complete documentation for VolumeDataAxisDescriptor. Got rid of the CoordinateRange since it's not really a range (i.e. Max can be smaller than Min) and documented this better. Fixed documentation for VolumeDataAccessManager::GetVolumeDataLayout().

Removed Access enum as it was not used (read/readwrite access is handled when you create the VolumeDataPageAccessor, not when you open the VDS).

on public Function and public Members

Refactored the Open/Close methods so there are alternate versions that take an IOManager instead of OpenOptions. This is meant to make it easier to test the code by creating IOManagers that e.g. store everything in memory instead of in an object store. Renamed the Destroy(handle) method to Close(handle) and added documentation for Open/Create/Close calls.

Fixed the HueVolumeDataRegionOverlappingChunk method so it adds the correct amount of ExtraValidVoxels when the target layout has different render margins from the source.
