Naming

[Noah-Kennedy]

In the middle of last year, I put out another registry called freighter which has since been moved to the Cloudflare GitHub org: https://github.com/cloudflare/freighter

This has been around for a bit now (since the middle of last year) and has seen significant use within the community under this name for a number of months now.

For various reasons, deploying to the freighter crate name on GH has not happened yet, but is slated to happen soon. We already have deployed a number of freighter- crates on crates.io.

It's probably best to rename this crate given that this will cause some confusion.

PS: I'm terribly sorry, I should have probably placed a warning marker on the freighter crate entry on crates.io.
