Option to show doc.province when displaying regional frequencies

[Lithodeas]

It would be very valuable if the regional frequencies were not limited to doc.region, but if doc.province could also be displayed, perhaps with the option to toggle it on the map, if that is feasible.

In TD (Theresas Dashboard) T(irol) and V(orarlberg) are displayed as separate entities in the region-view

[ctot-nondef]

this information is currently only available for western austria (tyrolia, vorarlberg, corinthia)
can be added for other regions subsequently

requires

• an additional Regions Search with doc.province as ml1attr
• adjustment of the result map to display the provinces/federal states accordingly

[ctot-nondef]

normalization does not work properly in a mixed display, only possiblity would be to display them exclusively where available
