events in the upload-pin-transcode loop

[jellegerbrandy]

For the UX in the frontend, we'd need at least:

• onFileReady(file) when the file is uploaded to the local ipfs node. We need this so we can start working with the hash
• onUploadReady(file) when the file has been successfully uploaded to the network. In practice, this means when the "pinning" node (in our current setup the transcoder) has the file available (but has not transcoded yet). This is a very important event to have, because it means that he user can leave.
• onUploadProgress(..) progress when the file is being uploaded to the pinning node.
• onTranscodingDone(ipfsHashOfTranscodedFile): when transcoding is done
• onTranscodingProgress(...)

@ya7ya , you think this is feasible with the protocol? Or shall we do this via some contracts?

[jellegerbrandy]

Of these events, we only have onFileReady and onTransocdingDone.

We can mock the other events in paratii-lib, so that we can progress in the frontend

clocking this, as we have most of this, but with better names :-)
