Display for uncertain metre identification

[danbalogh]

As per EGD §2.3.4, when the metre of a stanza is identified with uncertainty, we (in compliance with EpiDoc) add <certainty match="../@met" locus="value"/> as the first child element of the relevant <lg>. Arlo has noticed that there is no display for this. See e.g. https://dharmalekha.info/texts/INSIDENKKayumwungan stanza 10 (also e.g. https://dharmalekha.info/texts/INSVengiCalukya00052 stanzas 24 and 26). When you have time (I don't think this is urgent), please implement display. My suggestion is to add (?) after the name of the metre, e.g. X. Gīti(?)
