v0.5.1

This is a bugfix since a stitch * -v, as proposed in the readme, will lead to an error.
This is since os.mkdir is called before the wildcards are resolved, making opencv wanting to read the directory name, which leads to an error.
The tests did not catch this since there we don't use * but always a combination of filenames and wildcards.

What's Changed

Bugfix

• resolve wildcard in cli since created directory will lead to an error if wildcards are solved later by @lukasalexanderweber in #150
