v0.7.17

• bump minimum Rust version to 1.79.
• in UI's list view, add a tooltip on the end time which shows why the
  recording ended.
• fix #121:
  iPhone live view.
• update to hyper and http version 1.0. In the process, no longer wait for
  pending HTTP requests on shutdown. This just extended the time Moonfire was
  running without streaming.
• upgrade to Retina 0.4.10, adding support for recording MJPEG video. Note
  major browsers do not support playback of MJPEG videos, however.
