since we're using the generic call-tokenuri strategy now, can the logs-to-subgraph strategy be deleted?

• we've been successfully using the call-tokenuri strategy now: https://github.com/neume-network/data/blob/9b969d0c035816aff82eebbd206320134e7866d2/steps/3.mjs
• and so logs-to-subgraph isn't useful anymore: https://github.com/neume-network/data/issues/65
• can we delete it in the strategies repository? if so we should do it
