Feature description

As mentioned in this stackexchange post https://gis.stackexchange.com/questions/392878/how-to-construct-a-line-tangent-to-a-curve-from-a-point-using-pyqgis

Also don't recall it is possible in the GUI also

I have also wanted to have the ability to do this by just clicking on the point and be tangent to a circle or spiral
