Fix KeyErrors when reading data associated to supplementary AB data, namely:
in BLOCK_7:
- key 132: single channel spectrum of the sample ->
ScSm_(1) - key 136: Interferogram of the sample ->
IgSm_(1)
in BLOCK_11:
- 132: single channel spectrum of the reference:
ScRf_(1) - 136: Interferogram of the reference:
IgRf_(1)
in BLOCK_23:
- 132:
ScSm_(1) Data Parameter, - 136:
IgSm_(1) Data Parameter
in BLOCK_27:
- 132:
ScRf_(1) Data Parameter, - 136:
IgRf_(1) Data Parameter
