Muon digi opt2

Following a discussion with Mingshui today (1/mar/2025), in preparison of the physics sample production, this MR is going to do the following updates:

1. A further optimisation of the muon digi codes, fix several mistakes.
2. Define muon reco hit using a super-layer (i.e. with 2 layers crossing parpendicularly) Output muon reco hits with (x,y,z) position with a spacial resolution of 1_4_4 cm.
3. Ghost hits are simulated and stored when more than two hits firing the same superlayer, i.e. when ambiguity happens according to the geometry.
