As written in the changelog: Live streams formerly worked around a
Firefox pixel aspect ratio bug by forcing all videos to 16:9, which
dramatically distorted 9:16 camera views. Playback didn't, so anamorphic
videos looked correct on Chrome but slightly stretched on Firefox. Now
both live streams and playback are fully correct on all browsers.
I spotted this by inspection: adding a media time and wall time didn't
look right. I also confirmed the brokenness on my primary NVR:
```
sqlite> .mode column
sqlite> select
...> r1.composite_id,
...> r1.prev_media_duration_90k,
...> r1.wall_duration_90k,
...> r1.media_duration_delta_90k,
...> r2.composite_id,
...> r2.prev_media_duration_90k
...> from
...> recording r1 join recording r2 on (r1.composite_id = r2.composite_id - 1)
...> where
...> r1.prev_media_duration_90k + r1.wall_duration_90k + r1.media_duration_delta_90k !=
...> r2.prev_media_duration_90k
...> limit 5;

```
In the first row, the second recording's prev_media_duration_90k is the
first's prev_media_duration_90k plus its wall time, not its media time.
The CI nightly builds had been broken with the following error:
```
error: custom inner attributes are unstable

10 | #![rustfmt::skip]
| ^^^^^^^^^^^^^

= note: `#[deny(soft_unstable)]` on by default
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #64266 <https://github.com/rust-lang/rust/issues/64266>
```
I'd thought this was by mistake given that #[rustfmt::skip] is still
advertised on rustfmt's github page, but maybe not. Looks like
rust-protobuf's newest version uses
`#![cfg_attr(rustfmt, rustfmt::skip)]` to avoid this error.
Also fix a warning on nightly about an extraneous semicolon.
