Missing types after ol 7 update

[bozhidarc]

Hi I found the following missing types after the release of OL 7.
I think those can be fixed by replacing them with ReturnType<Geometry["getType"]> and ReturnType<Overlay["getPositioning"]

Error: node_modules/@types/ol-ext/overlay/Popup.d.ts:84:33 - error TS2304: Cannot find name 'OverlayPositioning'.

84     setPositioning(pos?: typeof OverlayPositioning | string): void;
                                   ~~~~~~~~~~~~~~~~~~


Error: node_modules/@types/ol-ext/overlay/Tooltip.d.ts:5:32 - error TS2307: Cannot find module 'ol/OverlayPositioning' or its corresponding type declarations.

5 import OverlayPositioning from 'ol/OverlayPositioning';
                                 ~~~~~~~~~~~~~~~~~~~~~~~

Thanks. OverlayPositioninig as been renamed to Positioninig.
I also found some issues in the examples
Viglino/ol-ext#855

WIP: #96
I currently still have troubles getting the examples up and running. If you have any idea

I just released a version 3.0.0 which is now compatible with ol.ext 4.0.1 and ol7
