refactor(iroh-base)!: move tickets into their own crate

[dignifiedquire]

Description

These now live in https://github.com/n0-computer/iroh-tickets and will be published as iroh-tickets.

Breaking Changes

• iroh-base::ticket has been removed

Notes

The 0rtt and transfer examples now use just EndpointIds to connect, and not tickets anymore. Otherwise we end up in a problematic dependency tree. If necessary I can add direct addresses and relay urls to the transfer example again

Seems fine.

Often to use tickets you had to explicitly import iroh-base, since they were not reexported by iroh. So it is not too inconvenient to depend on another crate.

I've made a PR n0-computer/chuck#80 to update netsim to use the endpoint ID. However many of those are air gaped and don't have standard discovery mechanics available. The ticked contained direct addr info which was needed for it to work in this environment. Dunno if relay url is needed because they all are configured to the same test spawned one so that should be fine I think.

You can keep re-running this job till it passes with your changes to check:

I'd propose to just use https://github.com/n0-computer/iroh-tickets in chuck then, no need to make it use discovery.

I can also add manual passing of ip addrs to the example if that's what we need for chuck
