ocrd_page: invalidate AlternativeImages automatically…

- whenever overwriting `Border`'s `Coords` or `Coords/@points`,
  remove all the `Page`'s derived images with `cropped`
- whenever overwriting `Region`'s or `TextLine`'s or `Word`'s
  or `Glyph`'s `Coords` or `Coords/@points`,
  remove all its derived images
- whenever overwriting `Page`'s or `Region`'s `@orientation`,
  remove all its derived images with `deskewed`
- add a warning to the GdsCollector each time
