feat: use blob-fetcher lib (#105)

Uses `@web3-storage/blob-fetcher`, `@web3-storage/public-bucket` and
`multipart-byte-range` to simplify code and ensure that freeway uses the
same code as hoverboard to fetch blocks via HTTP range requests informed
by location content claims.

This removes the content claims code from the existing R2 blockstore so
that it can be decomssioned more easily as there is clean separation
between new world and old world.
