Auto-Save Project and PrinterStudio Support

This release been in the works for a little while - thanks for your patience! It release includes the following new features:

• The tool will now periodically save your project to your MakePlayingCards (or PrinterStudio) account throughout the upload process. This is intended to minimise time wastage from the scenario where the tool encounters an error halfway through an auto-fill process. It'll auto-save your project by default but you can opt out of this behaviour.
• The tool now supports uploading your project to https://printerstudio.com and https://printerstudio.de - thanks to @lukegothic for the initial contribution here!
  • We can investigate adding support for the other regional variants of https://printerstudio.com - please create a GitHub Issue if that's something you're interested in.

And it includes the following bugfixes:

• There have been several improvements to the stability of the --skipsetup flag - this has been pretty broken for a long time and I apologise for that - please let me know if you continue to encounter issues with it!
• We've made an internal change which fixes Brave support - thanks for your patience with this! I expect there to be fewer random breakages like this on the webdriver front going forward.

Please refer to the instructions here for how to run the application on each platform.
