Image aligning still not working properly

[xtrojak]

There are still cases when forms aligning is not working. Sometimes not the most outer corners are considered. Perhaps we need to make our own implementation, without relying on external libraries. This way we can also try to solve #38.

There are still cases when some of the outer border corners are not detected at all.

Currently, the alignment works in ~99% cases. For future development to push this to perfection, we can consider:

• first run OCR annotation and do alignment based on some artefacts (basically Fiducial marker)
  • these are possibly not always detected, but if we use enough of them, it should be okay
  • then alignment is done separately for every service
• another option (easier) - work with distance between detected points
  • if they are different, try to change the sensitivity parameters of employed alignment library
• possibley enforce proper Fiducial marker in the future
