Allow tables and graphics between treatment sections

see comment at https://github.com/plazi/FNSO/issues/16#issuecomment-1400147744

We also noticed that a treatment cannot have a text or a figure without it being in tp:treatment-sec. I had an example of an article where I had this issue, is there any way to keep them?
