Enhancement: h4toh5 splits an attribute into several pieces if an attribute is too long. (override Revision #387)

As mentioned in Revision #387, a long attribute makes problems. Previously, only a global SDS attribute was handled. Now, any long attribute from Image, Vgroup, Vdata, SDS, and annotations is handled. Previously, an attribute becomes a dataset to avoid the limitation, but this changelist overrides this, and splits it into several attributes.

Currently, the naming convention is underscore + three digits; e.g., attr_001, attr_002, etc.
