Version 1.0

[sezelt]

This updates the version to 1.0.0 and from now on will use semantic versioning.

New features:

• Reader for Arina H5 files
• EMPAD2 reader shows progress bar in the main window (requires empad2 version 0.999)
• Complex FFT view
• H5 files (including modern matlab files) with flattened data are now read, and a dialog asks the user for the size. The resize dialog can be invoked at any time, to handle cases when the automatic shape finding for some py4DSTEM readers fails.
• Image statistics are now shown by hovering over the bottom bar. This will be revamped slightly in the future to also enable pixelwise data to be read off.
• When switching between different realspace detectors, a bug that caused the detector to be placed outside the viewbox has been fixed.
