changed get_lps to get_ets (consistent treatment of internal names as abbreviation of electoral term)
designed get_ets analogously to get_profession_groups, but offer more flexibility:
function offers option to choose (dummy parameter) whether the output format is in dummy form or a list (that is a data.framecolumn)
2. merge parameter either returns the whole input data frame including the newly generated columns or just the generated column(s)
