Fetch Farcaster data from Neynar

[DistributedDoge]

Neynar provides good source of farcaster data accessible via bulk REST queries. Using that I can scan ETH addresses in batches of 350 to return associated stats.

Interesting information to grab:

• FarcasterID for any ethereum address
• follower and follows count
• activity_status and power_user_badge

This answers questions such as:

• how many donors to round X or grant Y actually use farcaster?
• as grant manager, are applicants to my round on same "social media power-level"?
• as grantee how does farcaster following compare to donations?

TODO:

• [x] Estimate how many compute units are consumed per each API request
• [x] NeynarAPI resource to interact with an API
• [x] farcaster_profiles asset with rough stats display_name, following_count, follower_count for Gitcoin grantees
• [ ] farcaster_channels asset that tracks popularity of some topics like Gitcoin / Giveth / Optimism

Alternative would be to grab this data from os-observer, but I feel Neynar subscription is more flexible and allows for writes to Farcaster as well!

Any thoughts on how to use the writes feature? :eyes:

Using POST cast endpoint we can have a bot that posts weekly status updates in style used by Gitcoin for major rounds.

Something like that but focused on growth not totals:

Allo Growth since last week: 4 new rounds 20 new projects (5 use farcaster), 200 new donors (25 use farcaster), 2000 new donations.
