Set the start number in representation to the segment index that is sent by muxer.
With this enhancement, you can now specify the initial sequence number
to be used on the generated segments when calling the packager.
With the old implementation, it was always starting with "1".

An updated version of PR #1027
That previous PR was done using 2021 code, and there were many changes
in the codebase from there, so a rebase was needed and also some minor
tweak here and there. But it's the same code, just reimplemented on a
newer codebase.
If you want to take a look at this in action, after building shaka
packager with this PR's code included, try this commands in 3 different
simultaneous bash sessions:
1. Video UDP input: `ffmpeg -f lavfi -re -i
"testsrc=s=320x240:r=30,format=yuv420p" -c:v h264 -sc_threshold 0 -g 30
-keyint_min 30 -r 30 -a53cc 1 -b:v 150k -preset ultrafast -r 30 -f
mpegts "udp://127.0.0.1:10000?pkt_size=1316"`
2. WebVTT UDP input: `for sec in $(seq 0 9999) ; do printf
"%02d:%02d.000 --> %02d:%02d.000\ntest second ${sec}\n\n" "$(( ${sec} /
60 ))" "$(( ${sec} % 60 ))" "$(( (${sec} + 1) / 60 ))" "$(( (${sec} + 1)
% 60 ))" ; sleep 1 ; done > /dev/udp/127.0.0.1/12345`
3. shaka packager command line: `timeout 60
path/to/build/packager/packager
'in=udp://127.0.0.1:10000?timeout=8000000,stream_selector=0,init_segment=240_init.m4s,segment_template=240_$Number%09d$.m4s,bandwidth=150000'
'in=udp://127.0.0.1:12345?timeout=8000000,stream_selector=0,input_format=webvtt,format=webvtt+mp4,init_segment=text_init.m4s,segment_template=text_$Number%09d$.m4s,language=eng,dash_roles=subtitle'
--mpd_output ./manifest.mpd --segment_duration 3.2
--suggested_presentation_delay 3.2 --min_buffer_time 3.2
--minimum_update_period 3.2 --time_shift_buffer_depth 60
--preserved_segments_outside_live_window 1 --default_language=eng
--dump_stream_info 2>&1`
Note the added `input_format=webvtt` to the shaka packager command's
second selector. That's new from this PR. If you don't use that, shaka's
format autodetection will not detect the webvtt format from the input,
as explained in
https://github.com/shaka-project/shaka-packager/issues/685#issuecomment-1029407191.
Try the command without it if you want to.

adds an optional `--hls_start_time_offset` parameter, that, when
used, adds `EXT-X-START` tags to the HLS media playlists.
The EXT-X-START tag allows to specify the location where the player
starts playing, either from start (positive value) or from end (negative
value).
This is especially useful in case of livestreams where this tag can be
used to set the target latency of the playback.
Reference: https://datatracker.ietf.org/doc/html/rfc8216#section-4.3.5.2
The RFC says, that the `EXT-X-START` tag could also be added to the
master playlist, but my tests have shown that most players only respect
it when it's in the media playlists.
Fixes#970

This will force the muxer to order streams in the order given on the

A positive value, in milliseconds. It is the threshold used to determine
if we should assume that the text stream actually starts at time zero.
If the first sample comes before default_text_zero_bias_ms, then the
start will be padded as the stream is assumed to start at zero. If the
first sample comes after default_text_zero_bias_ms then the start of the
stream will not be padded as we cannot assume the start time of the
stream.
This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.
