Improve the line and column numbering in the text viewer

[geoffroy-noel-ddh]

Inscriptions 827 & 613 have column breaks.

Which should appear as column label in the text display.

Additionally the display of line labels should better follow the label in the n attribute.
Some special cases:

n=0: for a line at the beginning or end of a section (e.g. column) which is not transcribed (e.g. not legible, damaged or missing).

n=13a: for a line at the end of a section.

These are epidoc conventions.

Inscription 1040 has texpart divs <div type="textpart" subtype="fragment-physical" n="a"> and @n="b". In each textpart div the lbs are numbered from 1 onwards.

For comparison, 1485 has texpart divs (different subtype value but also numbered a, b, c, etc.) which have sequential numbers on the lbs; these are displayed with a blank line between the textpart divs which works very well.

Inscription 2945 has a lb n=0.

Inscription 4407 has cbs.

Hi @simonastoyanova , this should be fixed now. You can close if you are happy with resolution.
