Notes field on LentItem

[tribut]

While implementing a simple cli app using libopac, I noticed there is no way to access the additional information displayed in the account page ("Dieses Medium wurde bereits 3 mal verlängert", "Eine Verlängerung ist noch nicht möglich"):

My proposal would be to add an additional string field to LentItem (notes? statusText?). I could provide a PR that implements this for SISIS (Stb. Chemnitz), but wanted to make sure this is something you are interested in.

Thanks for all your work!

Yes, I think we could add something like that. My gut says statusNote, but I don't have strong feelings about this.
