Refactoring BLITZ

[irkri]

• ROI and TOF visbile at the same time
• Icon: plasma discharge

The icon is now added in two different ways:

• As the app icon by compilation of the app, using pyinstaller --noconsole --windowed --icon=resources/icon/blitz.ico blitz.py.
• As the window icon by using pyrcc5 to compile /resources/resources.qrc into blitz/resources.py. The python file needs to be imported at the place where the icon is set, using QIcon(":/icon/blitz.ico").

The way the data is masked changed. No additional numpy array is saved. Just the coordinates of the mask change internally. It is no longer possible to mask the data while it is transposed or flipped in any way. Repeatedly masking is allowed.

There is a new option to only update the ROI on drop (and not while still dragging). Also, ROI and TOF data will now be shown in the same plot.

The key combination Strg+C now copies the content of the lower right label (position of the mouse and value at this position) to the clipboard.

I changed the colors and font sizes of the option tabs. They are still not optimal, but its okay.

I figure that the code now is releasable. The .exe for Windows applications can be put together with the code into a new release. This will be version 1.0.0. TODO: Put the version somewhere in the code itself.
