[sugizo]

nice to have more tunings
ref
https://en.wikipedia.org/wiki/List_of_guitar_tunings

thanks

[sugizo]

test added

• guitars : 8 strings, 9 strings, 10 strings and 12 strings
• bass : 4 strings, 5 strings, 6 strings

also revise some name : regular tuning into standard tuning, dropped into drop
and also the tuning display sequence is not right, but already raise an issue about that
will add more after error reported below fixed (same error reported, but it's on different tuning about fret mark and fret added on left side)
