Missing assets API client

[DavideWalder]

I couldn't find a client to manage assets (specifically logos), is there one? I saw that there is documentation for it: https://docs.zitadel.com/docs/apis/assets, but it is not listed here: https://github.com/zitadel/zitadel-go/tree/v2.0.0-v2-alpha.9/pkg/client

I think at the moment the zitadel-go client only exposes the gRPC APIs.

The Assets API however is only Rest based since we had some problems around body sizes with gRPC.

Correct me if I am wrong @livio-a or @adlerhurst @hifabienne
