Adapt Curve v1 Base Pool to Work with RAI #6

Challenge Description
Adapt the Curve v1 two coin pool implementation so it can work for a pool with a peggie and a non-peggie (such as RAI). Template code for this pool type can be found here. You can take inspiration from the RAI Metapool code.
Curve gained lots of momentum in the Ethereum space with their efficient design used to swap similar tokens such as DAI and USDC. Reflexer would like to integrate RAI in Curve v1 but there's an issue: RAI is not pegged to $1 similar to tokens such as DAI. Instead, RAI has a "moving peg" called the redemption price.
In order to fetch RAI's redemption price, one has to first update it and then retrieve it. This is why the redemption price getter is not a view function. To make it easier to fetch the redemption price, you can use this contract that stores a slightly older version of the price or you can update and fetch the latest price from here.
