Update isolation DaVinciExample

Update option_davinci_tupling_relation_isovariables.py and related qmt test to provide a concrete and more complete example that shows how to get the track isolation variables extra particles (long tracks and neutrals) saved in TES location of the output file from the Hlt2 line Hlt2RD_BdToKstTauMu_KstToKPi_TauTo3Pi_OS implemented in Moore!2147 (merged).

The following example is planned to be extended by adding vertex isolation variables.

Since it is using another dst input, it should also address the issue presented here

NEEDS: Rec!3444 (merged), Analysis!996 (merged)

TODO:

• move the input file b_to_ksttaumu.dst and the tck manifest file to a more proper location
• update qmt test and complete example
