tempio needs to be added as a PATH

Brilliant Guide.  I've finally got Frigate running with a Coral USB!  after 2 years! 

I needed to add this path though

`/usr/local/tempio/bin`

```
addpath /usr/lib/btbn-ffmpeg/bin
addpath /usr/local/go2rtc/bin
addpath /usr/local/nginx/sbin
addpath /usr/local/tempio/bin
```

then it worked
