Configuration parameters:
    format: display format for this module
        (default '[\?color=state SUSPEND [\?if=state OFF|ON]]')
    lock_types: specify state to inhibit, comma separated list
        https://www.freedesktop.org/wiki/Software/systemd/inhibit/
        (default ['handle-lid-switch', 'idle', 'sleep'])
    thresholds: specify color thresholds to use
        (default [(True, 'bad'), (False, 'good')])

Format placeholders:
    {state} systemd suspend inhibitor state, eg True, False

Color thresholds:
    xxx: print a color based on the value of `xxx` placeholder
