Add message filtering capability

[Thomasvdam]

Motivation

Make indexing previously indexed state easier by skipping messages that have already been indexed.

Explanation of Changes

Optionally allow configuring a list of message types that are allowed to be published on the queue. Went for an allowlist as we'll generally use it when we want to reindex historical state and only publish updates for the new messages.

For the same reason I went for a simple slice of strings as the data structure; the list should never be long enough to matter in terms of performance.

Testing

Ran a local chain with the messages allowlist attribute set to account,account-balance

Logs:

2024-05-15T18:00:34.456+0800 [TRACE] publishing to queue: size=4
2024-05-15T18:00:34.456+0800 [TRACE] skipping message: type=supply
2024-05-15T18:00:34.456+0800 [TRACE] sending batch: size=3

And on the queue side we only received the account and account balance updates.

I suppose it would be more efficient to use a map for SqsClient.allowedMessages but I see your point that the list would be small anyways.
