Current PR fixes namespace representation, so it will be consistent with the passed one. Blob cmds require hex-based namespaces only now.

@vgonkivs commitment is still printed in base64 when hex is printed for namespace and string for data, is this intentionally left?

[vgonkivs]

Yes, non-base64 looks weird and it does not work with get methods !x\u003e\ufffd\ufffd\ufffd\ufffd\u001b\u000f\u0017r\ufffd{\ufffd\ufffd\ufffd\u001d\ufffdPk\u0006R\ufffdb\ufffd\ufffd\ufffd\ufffd\u001e\ufffd\u0007\ufffd
