[FEATURE] force_rhr expression function
...
Forces polygons to follow the right hand rule, in which the area that
is bounded by a polygon is to the right of the boundary. In particular,
the exterior ring is oriented in a clockwise direction and the
interior rings in a counter-clockwise direction.

[feature] Form context expressions in value relation widget
...
The value relation widget filter expression can now use two
new functions/variables that have access to the current
values and geometry of the form being edited.
This allows for dynamic filtering (drill-down) as explained
in the crowdfunding page:
https://north-road.com/drill-down-cascading-forms/
The new functions/variables are:
Function:
get_current_form_field_value( 'FIELD_NAME' )
Variable:
@current_form_geometry
