getLiquidityPools does not support filtering by 2 assets on VyFinance

[TwilightDuck]

let pools =(await dexter.newFetchRequest() .forAllDexs() .getLiquidityPools(djed, iusd))

This will correctly filter for Minswap and SundaeSwap but not for VyFinance.
And no pools for Muesliswap are showing up. (As referenced here: #17)

I think the all pools returned without filtering for assets for dex VYFinance is covered in #12
