multiple metadata accounts I am working on an app which parses many transactions using codama and as part of this I need to fetch IDLs for all programs in all instructions. As the only published method for fetching and parsing program-metadata content only supports single calls this results in many getAccountInfo calls which can exceed RPC rate limits for some suppliers. The addition of fetchAndParseAllMetadataContent which uses getMultipleAccounts to prefetch all PDA accounts, and additionally fetches all external accounts in a total of 2 RPC calls instead of potentially hundreds.

Nice, thanks for PRing these changes! I've made a few comments but overall it looks good to me. Looking at CI, it looks like you have a small linting issue to fix as well. Something about return await.
