James Allwright has upgraded the parser so it can now interpret
complex time signatures as shown in this example.
X:1
T: Example 1 using complex time signature
M:(3+2+2)/8
L:1/8
K:G
abc de fg|GGG aa bb|gfe GG FF|
In addition the handling of the L: field was improved.
This impacts abc2midi, yaps, abc2abc, and abcmatch.
The implementation of these changes involved creating a new
typedef structure (timesig_details) in abc.h, and numerous new
functions or upgrades in parseabc.c (check_power_of_two,
read_complex_has_timesig, read_L_unitlen, copy_timesig,
interpret_voice_label, ... Lots of changes to parseabc.h.
Minor changes to store.c, toabc.c yapstree.c to link to the
new functions in parseabc.c
