refactoring and CLI for presentation

[bertsky]

This is a first working version for an interface from METS to METS.

We might still need fiddle with the details (both in interface definition and implementation).

(One of the problems I saw was that ocrd_browser cannot show workspaces which still have remote images in them, see here.)

Note: for adaptation on the Kitodo.Production side, you will need the following patch:

(this will then have to go into data.zip again)

Yes, I thought of doing some of these name changes within this PR already (so we would only need to update the OCR script once). And we could indeed support more use cases than just Kitodo. But then again, we advertise this endeavor as Kitodo integration – why not heed our target users' naming expectations, and stay specific to the purpose? Nobody prevents other users from adapting the shell scripts to their own needs...

Mainly I am concerned about the naming in the script ocrd_lib.sh. I rather saw this lib as a fixed. So the user does not have to make any adjustments here. I think it would be good to keep the applications out of the lib cause of updateability of the ocrd_lib.sh script when updating OCRD Manager image. So that only adjustments in the scripts which use the library must be made.

[bertsky]

I see – agreed! Then lets move the arg parsers from ocrd_lib.sh to the top-level scripts.
