FIX: TremoloParser did not load/save imprData or torsion correctly.

• this error was introduced when incorporating local-global-maps and conversions where this was not correctly done for the improper and torsion string:
  • conversion from local to global on load was present but went over all atoms, not just newly parsed ones. adapt.. now gets atom vector as param.
  • save did no global-local conversion. For this we generalized adaptIdDependentDataString() to get a function pointer converting ids.
• TEST: We added a new regression test on this matter where a .data file with impropers is loaded and stored.
