Update INTER IDF for 2D detector

[rbauststfc]

• [x] The INTER IDF needs updating for their new 2D detector.
• [ ] The parameter file needs to be updated so that the default spectra that are applied when you select MultiDetectorAnalysis are relevant to the new detector (to be useful, this default should be the ROI that would usually be relevant after the summing step). The point detector will be removed, so we could consider removing the defaults for that, but we should definitely add the following to set the correct analysis mode by default:

<parameter name="AnalysisMode" type="string">
    <value val="MultiDetectorAnalysis"/>
</parameter>

With this we also need to consider that ROIDetectorIDs are now required to make the reduction useful for the INTER 2D detector as it triggers the required sum banks step. Therefore we may need to supply a default for this in the parameter file too.
