implement separate tpc values for transposed view
fix last commit
Fix layout of ambitus elements with accidentals.

Ambitus elements with accidental(s) are laid out misaligned with ambitus elements without accidental(s).

The new algorithm aligns the leftmost note heads of each ambitus and places accidentals accordingly.
Clean up code and correct octave detection in updateRange()
Fixes to ambitus:

- Fix missing adjustReadPos() for ambitus in Maesure::layoutX()

- Reduce left margin in there are accidentals
