#162 ligature display for more than 2 letters

[Elli Mylonas]

When encoding a ligature of more than 2 letters, the display seems to put a sling over each pair. It's not easy to see, because the sling character is of a fixed size.

Example: https://usepigraphy.brown.edu/projects/usep/inscription/VA.GladeSpring.PHHS.L.02-mdn/
Encoding: <hi rend="ligature">Ant</hi>o<hi rend="ligature">nini</hi><hi rend="ligature">an</hi><hi rend="ligature">ae</hi>
produces this display: A͡n͡ton͡i͡n͡ia͡na͡e which has too many ligature marks!

Is this a stylesheets problem?

InsLib uses an approach with ligatures that are generated via CSS, see e.g. the files global.css and htm-teihi.xsl in this commit: https://github.com/EpiDoc/Stylesheets/commit/8ec6c9f7250bf6e9d57bface0dc4ff7057e9438f

Would be good to consider porting this to the Stylesheets as a whole, but obviously need to check it doesn'tclash with anyone else's local handling of ligatures…

Irene, please can you make this (a bit more) global in the EpiDoc stylesheets? i.e change

<xsl:when test="$parm-edn-structure = 'inslib'"> on line 67 of htm-teihi.xsl to $parm-leiden-style=('london','usep') (or similar)
