Add transaction update error to Geyser plugin interface

[fardream]

Problem

Geyser plugin interface only supports errors for slot status update and account update. This PR adds support for transaction update error.

Summary of Changes

Add one more enum variant TransactionUpdateError to Geyser plugin's error enum.

i don't see where this is actually emitted or responded to by the streamer interface. Sounds like it's purely your implementation detail? If that's the case, please just use GesyerPluginError::Custom

I am following the example here in the Postgres DB plugin.

I think the error should be emitted when notify_transaction fails - looks like right now the Postgres DB plugin emits SlotUpdateError.

Yes. I think it is desirable to make this symmetric to the other major data we are streaming
