arranger.ly update

[Gilles Thibault]

Everything is said in the title (download links at the bottom of the 
message).
On the menu, mostly a lot of code cleaning, but also new functions and 
new features. They are all explained in the documentation which is 
directly accessible here:

   http://gillesth.free.fr/Lilypond/arranger-docs/arrangerDoc-en.pdf

New features :
   - positions: dotted duration values are now allowed:
       '(7 4.) for '(7 4 8)    ; bar 7 + a 4th + an 8th
     However, for 2 or 3 points, the syntax 4.2 or 4.3 should be used 
instead.
     ( 4.. or 4... are not scheme objects, unlike 4. )
       '(7 4.2) for '(7 4 8 16)
       '(7 2 -16) is of course still possible.
   - export-instruments has been remade. A line break is still done 
after each bar
     but some events such as multi-measure rests R1*... will not be 
splitted.
   - add-dynamics allows also the addition of dynamics in \grace 
sections, by
     the use of the colon character ":"
       "p:8" will produce { \grace { s8\p } <> }

New functions:
   - mmr for easy addition of multi-bar rests R1*...
   - seq-r for sequences with many rests r...
   - The following functions: signatures, keys and marks, are not 
absolutely essential,
     but they can avoid a lot of #{ #} typing when building \global in 
the beginning.

"Versioning": all .ly files required for arranging.ly will now share the 
same version number.
The current version is Y/M/D = 2021/06/20

That's it.
Happy downloading and exploring.
