We should remove this to ensure slow gateways that never error are deprioritized properly.

This approach is consistent with libp2p components, unixfs, ipns, etc. Since #281 and #284 were merged without review, this PR implements suggsestions that would have been in the review of those PRs. 1. Creation of block brokers is done by exported function. If your broker takes arguments, pass them to the factory function. The factory then returns a function that accepts helia components and returns the broker. 2. Removes BitswapBrokerFactory as it is redunant The internal API may need some more work but the external API should be relatively stable.
