Use unique channel names

[llucax]

What's needed?

When the client create new channels, it uses a fixed string f"raw-component-data-{component_id}", which means multiple instances of the client will use the same name for channels, which could be confusing/misleading when looking at the logs.

Proposed solution

Add some name to the API client itself so it can be used in the logs too, defaulting to some short hash that will be unlikely match the auto-generated hash of other API client instances.
