Optimize `store_get_asc_new`

[leoyvens]

This shows as a major time consumer in a few subgraphs including:
https://thegraph.com/hosted-service/subgraph/sushi-labs/users-polygon (Qma5YzDtseXGJfwt1dGMmRwMaqvbgdSgnprWSdnp5gQf3n)
https://thegraph.com/hosted-service/subgraph/sushi-labs/users-ethereum (QmV4tr3xCx21z77YhPNLM7dJJtGmQ7tvzKpLJTBHNrBd5B)
https://thegraph.com/hosted-service/subgraph/sushiswap/sushiswap-polygon (QmT3h6RJvw5zJ6Gq6v6xt1sNExxHcUXEXc4y9rGHjYmPFj)

Since this is purely a CPU operation it should be possible to benchmark it locally and hopefully make significant optimizations.

Great, this is a major blocker for us, we have a release planned and the sushiswap/sushiswap-polygon has only moved 1% in 3 days

Hey @leoyvens I was looking into this and store_get_asc_new is much less of a contributor to the metrics now for the users subgraph, but it is still a big contributor to QmT3h6RJvw5zJ6Gq6v6xt1sNExxHcUXEXc4y9rGHjYmPFj
Looks like the slow handler being triggered is onSync, @OlaStenberg can you point me towards the most recent code to dig into that?
