Robotframework-sikulixlibrary

- All find operations can define a region where to search for with the parameter `regionSelect`. The values are the same as in the keyword `Region SetDefaultSelectMode`. This is backward compatible with any previous find operations.
- It is now possible to manage the SikuliX logging and debug output through `Set Debug number`, where number is 0-3.
- Screen dimension is not anymore hardcoded to 1920x1080, thus should work with 4k screen also.
- New keywords to get text from a region and log a screenshot added.
- Various documentation improvements.
