    tdf#107350 - prevent crash in unotbl.cxx
    
    check pointer and throw exception instead of SIGABRT
    when reading data from text tables that have
    varying row &/or col lengths from
     - merged cells after first row,
     - split cells in first row, etc.
    
    add backstop safety check -> exception because
     - complexity check fails (wrong/not called)
     - OOo uno api doc calls for exception when
           text table is 'too complex'
    v2:  better error message for crash point and
           its parallel (getData[Array])
