BigQuery sender

[wikp]

This Pull Request introduces a BigQuery sender that utilizes BigQuery's Storage Write API. When dealing with JSON topics, it relies on the JsonStreamWriter. In other scenarios, it uses the SchemaAwareStreamWriter. Since these classes don't share a common root, we had to be creative with the structure of the classes.

Just a heads-up, this PR is currently in draft mode, meaning it still needs certain additions, like tests, among others.
