DerivationFrameworkInDet: Fixes DOAD_IDTIDE derivation format

The MR provides fixes for two small issues with the DAOD_IDTIDE format. Firstly it provides a conversion for the pixel ToT values so that these can be properly included, previously the aux variables were created but filled with zeroes. Secondly it removes the hard coding of the "ThinHitsOnTrack" property and instead takes the value from the "InDetDxAODFlags" so that this can be disabled in circumstances.

I have run RunTier0Tests.py on lxplus and the code seems to pass but I do not expect this as the DAOD_IDTIDE is generated directly at tier0 for data however the impact should be minimal, filling the pixel ToT values with sensible numbers instead of zeroes and the "ThinHitsOnTrack" defaults to true so in the absence of it being explicitly disabled the same behaviour will continue.
