Added support for more whole slide image formats

Bug fixes in the overlaying of cores.
More features. Cleaner code.

This version allows for moving of selected regions in the tissue array exporter.
There is also new windows in the thresholding window to show a higher resolution image.

This version has more options for saving additional figures alongside the image export - and probably more bugs!
I will iron out all the bugs in the next release hopefully...

This has the added integration of a figure and the ability to add patient metadata to the TMA cut scripts.
This should be useful for downstream applications.

This is the first release of the TMAPP digital pathology TMA exporter and analysis platform.
