Direct frame / sequence jump URL parameters (and CLA parameters)

[l4rs5chnyder]

Is your feature request related to a problem? Please describe.
We have several use-cases where we want to specifically show people a frame in the timeline.
Always sending them the URL (or RRD files) with an explanation to which timeline and timecode to jump is an annoyance on both sides.
It would be nice to allow the timeline frame to be passed to the URL (public or internal viewer) or CLA (as parameters) since, I assume, this is very similar.
However, we're particularly interested in the web-viewer use-case.

Describe the solution you'd like
E.g. an additional
&timeline={USER_TIMELINE}&tc={USER_TIMECODE}
in addition to the general
https://app.rerun.io/version/{RERUN_VERSION}/index.html?url={RRD_URL}

In addition, it might be beneficial to directly be able to specify start and end timecode as in

E.g. an additional &tc_end={USER_TIMECODE}
&timeline={USER_TIMELINE}&tc={USER_TIMECODE}&tc_end={USER_TIMECODE}

Describe alternatives you've considered
Not aware of any alternatives.

Additional context
No additional context. Let me know if you need more specific information.

• Allow configuring selected timeline & initial time from blueprint #7728

-> so far our thinking has been to have the selected time be a thing that is configured via blueprint. But having this accessible in URL/CLI parameters as well makes a lot of sense to me
