feat: add @helia/bitswap with sessions (#409)

Adds a `@helia/bitswap` module with code ported from `ipfs-bitswap` and greatly simplified.

- Supports sessions
- Only supports bitswap 1.2.0
- Uses libp2p's metrics system instead of a custom version
- Uses Helia's routing instead of libp2p to take advantage of http delegated routers that return bitswap providers
