[bisq-network/projects] Remove the need for Bisq to trust Bitcoin Average by querying exchange APIs directly and calculating our own weighted average for fiat and altcoin prices (#35)

[wiz]

Since the Bisq Pricenodes were all migrated to the new code, and Bisq is no longer using Bitcoin Average as a price oracle, calculating our own weighted averages (documented at https://bisq.wiki/Bisq_Price_Indices), I am closing this project as `was:delivered` - example of pricenode monitoring logs follow:
