[jorgenherje]

Update VectorCalculator based on enhancement/fix in SmartNodeSelector

Based on: equinor/webviz-core-components#178 and equinor/webviz-core-components#181

• With update of SmartNodeSelector with its suggestion popup placed on top, the VectorSelector utilized in VectorCalculator can be placed in an max height are or scroll field, as suggestion popup will not trigger scroll area.
• Add usage of "TreeData" and "TreeDataNode" as it is exported?
• Set case-insensitive search
• Set placeholder: "Add new vector..."

Consider also adding a dialog asking if the user wants to save changes when switching to a different expression in the list and not having saved changes yet.

• When external parsing is utilized, the default expression for "New expression" should be parsed/validated? Now it shows valid and is not parsed until editing is started
• Fix textcolor when hovering buttons. white text becomes black (buttons with dark background color) - only in Dash
