Remove range.assignment and range.diaIDs

[lpatiny]

Currently we have similar properties at the level of the Range1D and Signal1D. Those are assignment and diaIDs. This is not that user friendly and we want to get rid of the one at the level of range.

We should deprecated / suppress the following 2 properties

  assignment?: string;
  diaIDs?: string[];

And keep the following 3 properties

  atoms?: number[];
  assignment?: string;
  diaIDs?: string[];
