For all downstream repositories of core, @neume-network/schema should be a peerDependency

[TimDaub]

• We're again in npm version hell as @neume-network/schema is now being used everywhere individually
  • https://github.com/neume-network/core/blob/1cd0595ee009dc109c00855966407561686193cc/package.json#L39
  • https://github.com/neume-network/strategies/blob/54631d99cbb1861c9c1381a7b0d5209da7465518/package.json#L50
  • https://github.com/neume-network/extraction-worker/blob/ed02ece7d6487363cc8c3db0207ffd979574f66c/package.json#L62
• We once had the same problem with eth-fun until we just said that we make it a mandatory peer dependency in all downstream packages (strategies, extraction worker) and that we truly require it for @neume-network/core though
• This has worked well IMO and so we should do the same now with @neume-network/schema
