Usage
$ convertio -f jpg ./some-image-with-hyphen.png
Expected result
The API will convert some-image-with-hyphen.png to some-image-with-hyphen.jpg.
Actual result
Error:
No readable input files
Reason
In class CLIOptions is a regex used that checks arguments against -(\w+) and if matching the argument is considered an option.
I fixed that and will provide a pull request in a couple of minutes.
