hanatToVolume doesn't catch non-existant column names with a useful error message #242

Naive usage of hanatToVolume expecting same naming as anatLmer volumes resulted in a not-helpful error:

stats <- hanatToVolume(magmodel, labelVol, "tvalue-genotype2:age")
Error in replaceValues(labelVolume, out, labels, values) :
 Not compatible with requested type: [type=NULL; target=double].

Added a column name check for this
