  • Swaps the assumed coordinate order from NEU to ENU,
  • use transformed (model) coordinates as topocentric origin, to effectively compute residuals as residual = target-model instead of the other way round.

In the output methods `create_geojson_file` and `as_markdown` there is
an implicit assumption about the order of coordinates in the structure
`self._data["residuals"]`.
Proj outputs coordinates in ENU order, hence, the assumption has been
changed accordingly.
This effectively means that ENU-residuals are now computed as

residual = target - model

which is the usual way, and what is in fact done in the rest of the code base.
