AAX fetchIndexOHLCV, fetchMarkOHLCV, fetchPremiumIndexOHLCV

Removed fetchIndexOHLCV, fetchPremiumIndexOHLCV and fetchMarkOHLCV and set them to false. AAX doesn't have an endpoint for fetchMarkOHLCV and fetchPremiumIndexOHLCV. There is an endpoint for fetchIndexOHLCV but it only returns a single candlestick so I set it to false also.
