Adding a new feed

1. Get familiar with some medium articles to understand the pitfalls and security concerns when using an oracle and designing a robust settlement price. https://medium.com/tellor/best-practices-for-oracle-users-on-ethereum-1ad9e2a43c3b

2. Look through how tellor works

3. Open a TIP proposal(see previous PRs for an example) https://github.com/tellor-io/TIPs

4.The final step is to open a PR to implement it in telliot which users use to submit the values. add the APIs used to extract the values in: https://github.com/tellor-io/telliot/blob/master/configs/indexes.json add the new Data ID to push to the oracle contract: https://github.com/tellor-io/telliot/blob/master/pkg/tracker/psrs.go 5. We will announce the new Data ID in the communication channels so that miners know that they need to start pushing this new feed.
