feat: support for async sdk types

[hallvictoria]

Description

In order to support aio blob client types, the decode() method needs to be async. This is currently not supported, because the from_incoming_proto() method in the worker, where decode() is called, is a sync call.

This changes from_incoming_proto() to be an async method instead.

Tests are added for the new async blob client types to test this change. These new tests will fail until a new blob extension version with the aio types is released.
