Missing glyphs for German lute tablature

[rettinghaus]

Currently the German Renaissance lute tablature contains 23 *Lower glyphs (Carolingian minuscules), but actually 25 letters were used for the first 5 frets of the first 5 courses.

See following example taken from Sebastian Virdung: Musica getutscht vnd auszgezoge, 1511:

For last two missing courses in the 5th fret tironian notes have been used, the et and con:

They can be seen in action e.g. in Hans Newsidler: Ein Newgeordent Künstlich Lautenbuch:

So I propose to add these glyphs to the range:

(tironian et) as U+EC24, luteGermanEt, 2nd course, 5th fret (et)

(tironian con) as U+EC25, luteGermanCon, 1st course, 5th fret (con)
