While running kurtosis and spamoor, I noticed occasional `null` entries
coming back from `getBlobsV2`. After investigating, I found that spamoor
can use the same blob data across multiple transactions, so with larger
blob counts, there's an increased chance that a blob is included in a
block more than once. As a result, previous indexes in the hash-to-index
map in `getBlobsV2` would get overwritten.

I changed the map from `map[common.Hash]int` to `map[common.Hash][]int`
to handle this case. I decided to go this route because it's the
smallest-possible fix, but it could also make sense to update
`blobpool.GetBlobs` to de-duplicate the hashes.
