[FEAT] Support the FeedRegistry on BSC

[wmitsuda]

According to the docs, Chainlink currently only supports the FeedRegistry contract on ethereum mainnet and kovan.

Some BSC users of my project would like to see token prices in USD, but it is not possible since there is no feed registry.

You can still use the price feeds contracts, but you'd just need to get the contract addresses outside the registry.

yes, I know that, the point of this issue is to ask for the FeedRegistry to be available on bsc, I don’t want to get the addresses outside the registry and have to hardcode them

could you reopen it?

Ah, I see. I'm leaving it closed and adding the "needs votes" label for others to upvote it.
