docs: Append one or more records to the end of a numpy recarray or ndarray .
  
      Can take a single record, void or tuple, or a list of records, voids or 
      tuples.
  
      Implemented by the tabarray method 
      :func:`tabular.tab.tabarray.addrecords`.
  
      **Parameters**
  
              **X** :  numpy ndarray with structured dtype or recarray
  
                      The array to add records to.
  
              **new** :  record, void or tuple, or list of them
  
                      Record(s) to add to `X`.
  
      **Returns**
  
              **out** :  numpy ndarray with structured dtype
  
                      New numpy array made up of `X` plus the new records.
