feat(geospatial): Add makeOBBFromRegion()

[ibgreen]

This is a restructuring of @sraimund 's work in PR #40 to resolve some intermodule dependencies and naming choices.

---

Here the ported code from Cesium to fix the calculation of the bounding box from a region on the WGS84 ellipsoid (see issue visgl/loaders.gl#3144). The function signature fromRegion() in oriented-bounding-box.ts (math.gl/culling) is similar to the previous createObbFromRegion function in bounding-volume.ts (loaders.gl/tiles). The other functions are nearly a 1:1 mapping from Cesium, except that these are now class methods.

Test:
https://stackblitz.com/edit/stackblitz-starters-pode72re (takes ~2mins to build and load)

Notes:

I could only build the culling module when adding // @ts-ignore // eslint-disable-next-line import/no-unresolved above import {Ellipsoid} from '@math.gl/geospatial'; in oriented-bounding-box.ts and import {Ellipsoid} from '@math.gl/geospatial'; in ellipsoid-tangent-plane.ts.

I'm not sure whether the 'lint' command worked correctly since it only showed some warnings for the dev-docs.
