[pshaiCmd] Super Smoother

SuperSmoother ported from a TradingView script.

Usage:

local hlc = HLCPrices()
local mean_line = OptimizedForInterval(0, || CC_SuperSmoother(hlc, 200, 50))

Plot(0, 'Mean', mean_line)

Usage (loop):

local markets = {'BTC', 'ETH', 'XRP'}
 
for i = 1, Count(markets) do
    local mkt = CreateMarket({baseCurrency = markets[i]})
    local hlc = HLCPrices(0, true, mkt)
    local mean_line = OptimizedForInterval(0, || CC_SuperSmoother(hlc, 200, 50, mkt))
 
    Plot(i, 'Mean - ' .. mkt, mean_line)
end
