Click dependency < 8.0.0

[poggenpower]

The CLI seems to have issues with the latest major release of click 8.0.0
With 7.1.2 it is working well.

As a quickfix I will submit a PR to set the dependency to click==7.1.2.

From the recent release notes:
https://click.palletsprojects.com/en/8.0.x/changes/#version-8-0

Redesign the shell completion system. #1484, #1622

Support Bash >= 4.4, Zsh, and Fish, with the ability for extensions to add support for other shells.
Allow commands, groups, parameters, and types to override their completions suggestions.
Groups complete the names commands were registered with, which can differ from the name they were created with.
The autocompletion parameter for options and arguments is renamed to shell_complete. The function must take ctx, param, incomplete, must do matching rather than return all values, and must return a list of strings or a list of CompletionItem. The old name and behavior is deprecated and will be removed in 8.1.
The env var values used to start completion have changed order. The shell now comes first, such as {shell}source rather than source{shell}, and is always required.

Even if the release notes saying that the keyword "autocompletion" will be removed in 8.1 it seems to cause issues already in 8.0.x version. Therefore the pinning to the latest 7.x version.

Here the stacktrace if click>=8.0.4 is installed:

As per my comment in the PR, I've fixed this in code. Thanks for the heads-up!
