nrfutil does not work with python 3 for generating bootloader settings page

nrbrook

When nrfutil is installed with python 3, I get an error when generating bootloader settings page. This does not occur with python 2. As python 2 support expires very soon, will this be fixed soon?

Note: Generating a DFU settings page with backup page included.
This is only required for bootloaders from nRF5 SDK 15.1 and newer.
If you want to skip backup page generation, use --no-backup option.
