Moritz Barsnick 114bbb0b74 libavfilter/avf_showwaves: make sqrt and cbrt scale option values available to showwavespic by name The 'sqrt' and 'cbrt' scalers were added in commit `80262d8c86`, but their symbolic option values only made available to the showwaves filter, not showwavespic, despite the scalers working properly by their numerical option values.
