How to display HDOP/PDOP graph in rtkplot for .pos file?

Need so also load the observation and navigation data.

The .pos file does not have the information required - the satellite elevation and azimuth. The obs and nav files can be loaded along with the .pos file, the presentation would be the same. The DOP is not taken into account directly in generating the solution.

The stat file does have the satellite elevation and azimuth but this information is not currently used by rtkplot for the DOP etc, and that would still require an extra file to be generated and loaded.

There is a proposal in #713 that will show the DOP graph for the solution, using the solution satellites, but it does require that the solution stat file be generated. Currently just for the Qt rtkplot app.

There are now two variants of the DOP plots, one using the stats results which uses the satellites used in the solution, and another using the observation and navigation data that includes all satellites. In each case the satellites can be further narrow by filters and then a subset of the satellites are used to calculate the DOP. Is there something that does not appear to be working as expected?
