Just to briefly comment on search_supcell_size as I was just looking at that code: this variable is there to replace the hardcoded supcell constant in module w90_kmesh. This could be useful if the unit cell is very skewed. But currently, the implementation is incomplete, so it does not work (there is either a crash or garbage output if search_supcell_size /= 5). The fix is to replace all remaining supcell with search_supcell_size.
