Revert Embedded_data_specification Optional

In #328, we made the attribute `data_specification` in class `Embedded_data_specification` optional, since that is what we thought the specification said (See also the discussion in #326) However, this was a bug in the specification, which is fixed in v3.0.1 of the specification. We therefore revert these changes. Fixes #326
