Price Feed Pallet
This pallet is an abstraction over the chainlink-feed-pallet which provides oracle data from
the chainlink network. This requires some more configurations and provides prices for assets
used in the index. For the purpose of the PINT Index all prices will be using a single
denominating asset which will be one base currency, which maybe USD, so that the net asset value
of the index can be calculated. It is therefore assumed that all the registered chainlink feeds
are price pairs with a consisting asset price (e.g. USD as in USD/DOT). NOTE: Most
chainlink price feeds use USD as the quote currency to easily calculate how much USD is
needed to purchase one units of the base currency, or the value of a certain amount of assets
by multiplying it with the units the assets. Therefore ths price feed pallet sticks to the same
convention, so that the NAV of the index is the sum of all the assets multiplied with their
price in form of (Asset/USD) divided by the total supply of index tokens which essentially is
the currency price pair of (PINT/USD).
