fix MSVC/conda build
Created by: germasch
This simply renames helper::CopyMemory
to helper::CopyMemoryBlock
to
avoid a name clash with the CopyMemory
defined in the MSVC build in #1485 (closed).
@ax3l, it'd be great if you could check whether this fixes your problem, since it apparently doesn't happen with the MSVC builds that part of the ADIOS2 CI.
