Address inconsistent type self.colors returned by Click generating exception in cmd

[joswr1ght]

Noted in the tmuxp project, libtmux returns an error with the most recent versions of the Click library, where self.colors is a str not an int, leading to the error ValueError: Server.colors must equal 88 or 256. This PR casts the self.colors to an int to accommodate the inconsistency in Click.

Thanks

Is there a tmuxp issue to link this to? tmux-python/tmuxp#649, tmux-python/tmuxp#678

@mtrajano @joswr1ght Is this linked to a particular click version? How do we know this won't break systems that already working? Any tests?

[tony]

is this still relevant ATM? (after tmux-python/tmuxp#651?)

@tony apologies for the late response, this is not relevant after tmux-python/tmuxp#651 as you mentioned, it can be closed

@joswr1ght

Based on what @mtrajano, I assume this PR has been superseded by tmux-python/tmuxp#651

If that is not the case or the issue still persists please let me know

If not feel free to close this. If there's no objection I will close this weekend

[joswr1ght]

Thank you! Closing.
