Project: Core data feeds

[adamewozniak]

Some protocols on EVM require a push-style oracle with a chainlink interface. We will create push-style data feeds with these specs:

• Push at least every 24 hours
• If the current price deviates from the pushed price by X%, push the price feed
• Chainlink interface compatible
• Uses Axelar's GMP to push from Ojo -> EVM

In order to achieve this, we have to build a few things:

• Chainlink interface compatible contracts #35
• Axelar GMP relayer #36

And we also have to:

• Apply for Axelar's express gateway #38
• Update the website docs for core data feeds #37
