DisplayCAL 3.8.7.1 released

Fixed in this release:

• [Trivial] [UI] Profile information (Linux): When using wxPython 3.0 instead of 4.0, clicking the sash would throw an error (using wxPython 3.0 is deprecated).
• [Trivial] macOS: Only automatically re-enable black point compensation if restoring defaults or loading a non-3D-LUT preset.
• [Trivial] Profile loader (Windows): Work-around two instances of the profile loader being started after powering on the system if fast startup was enabled in Windows power settings.
