max_num_non_arccorrected_bins default=0 now raises error

[KrisThielemans]

This is the default

STIR/src/IO/InterfileHeader.cxx

Lines 590 to 591 in 8ced2d7

	max_num_non_arccorrected_bins = 0;
	default_num_arccorrected_bins = 0;

If the Interfile header does not contain the keyword, and does not recognise the originating system, we therefore raise an error

ERROR: ProjDataInfoCylindricalNoArcCorr: number of tangential positions exceeds the maximum number of non arc-corrected bins set for the scanner

It might make more sense to set it to the physically allowed maximum and write a warning. Due to interleaving, the max value is given by num_detectors_per_ring-1.
