NVS Entry and Namespace association
When a namespace entry is encountered in a CSV file, each following entry will be treated as part of that namespace
until the next namespace entry is found. At this point, all the following entries will be treated as part of the new
namespace.
Note: First entry in a CSV file should always be a namespace entry.

By default, binary blobs are allowed to span over multiple pages and are written in the format mentioned in Section
