Airdrop to Cosmos contributors

[faddat]

We should generally follow the approach taken by Celestia since there hasn't been a massive increase in airdrop farming spam of stuff on git.

I think that their code for this is open source, but even if it isn't I bet we can simply ask.

Personally I think that pull requests correcting spelling mistakes or other minor matters are in fact a public good, even if they're driven by desire for airdrops.

This should include:

• ibc-go contributors since Jan 1 2022
• SDK contributors since Jan 1 2022
• all wasmd contributors
• contributors to osmosis
• token factory contributors
• comet contributors
• iavl contributors
• Certain individuals by fiat

hey @tnv1 -- I think we should bump this into the future.

We could do it in v2 by governance propsoal and save a lot of complexity
