feat: example video review application based on motion recordings (#77)

* get_motion_files: take channel as argument

For "TrackMix" with two lenses, channel 0 is the wide-angle lens while channel 1 is the telephotolens.

The "action" parameter of the Search request is documented in Reolink's PDF as being "0", yet this code passes "1". Not modified in this change as it did not seem to prevent correct operation on my trackmix wifi.

* download_motions: various fixes

- use https (needed on Trackmix wifi)
- download videos from the start of today until right now (search cannot span more than a given day)
- download videos from the start of yesterday until start of today (to get good coverage, given that spanning more than a day is impossible)
- search videos for both channels in main stream
- write file names to disk as they are on the camera for later parsing

* examples: add Video Review GUI
