Add "full-timeseries-journey" option to use the full timeseries for the journey

Used for when you have video clips from a longer gpx track and so want to display the entire journey still

Need to be a bit cleverer with this for the moving journey map so it draws the entire gpx but only downloads that needed for the video. Shouldn't be too hard, will update.

What is hard and I think beyond me is to support the full gpx for the elevation as that's too closely integrated with the video frames

Thanks for this. I think maybe you have given me an idea...

[jburnhams]

Just realised the "odo" metric doesn't use the entire gpx either so perhaps widgets do need to support the fulltimeseries too, plus then can do elevation graph which I'd like. I'll have a look into it at some point unless you think you'd be able to soon?

Hiya, thanks for this contribution. I will definitely take a look at it, but i don't know if I can merge it as-is. I do think want you to spend time unnecessarily, so please don't go too far in one direction before we can establish that it's the one we want the code to go in.

[jburnhams]

Oh don't worry about that, i'm making the changes for myself, just a bonus if you get any use from them too. I'll need odo to use the entire gpx track so was just if you thought you might do that soon then i'd hold off on giving it a go myself

@jburnhams thanks for this feature! I really needed it, I started looking at the code to add it for me, and saw that you had already done it! Super!

I’ll just describe my use case to show why this option is needed, and it’s worth finishing it.
I have quite long routes (several hours), but I don’t need to record a video of the entire route, I’m only interested in certain sections. But in order to get beautiful widgets, I have to record a video of the entire route, then create widgets, and then cut the pieces and join them together.
The solution to write separately GPX (for example, in a phone) and short files looks ideal, but with this option the journey widget (and gradient too) turns out to be not at all interesting.
This option completely solves my problem.

I've also been experimenting with a similar code change for my videos. My use case is similar where I record the full activity on a cycling head unit, but only take short videos as I'm riding which I then stitch together (see https://www.youtube.com/watch?v=gXQso0IHino for an example).

The only way to display the full map from the gpx/fit file is to do something similar as this PR which makes the full timeseries available to the journey map widget, rather than just the portion of the timeseries that matches the original video.
