### Steps to reproduce the problem
1. install lastest inkscape (1.0-x)
2. launch hardcode-tray via `sudo hardcode-tray --theme Papirus --conversion-tool Inkscape`
3. Python freak out.

Reproduce the failure with `sudo hardcode-tray --theme Papirus --conversion-tool Inkscape`, then inspect `HardcodeTray/modules/svg/svg.py` and the `get_pngbytes` call in `HardcodeTray/utils.py`. Done means the Inkscape conversion produces the expected temporary PNG and the Bitwarden icon replacement completes without the `FileNotFoundError`.
