Add KMZ as a log file

[brunoolivieri]

This PR adds a KMZ downloadable file for each .Tlog generated the file by running a script on OS boot.

~~note: That is a WIP, I tested on Ubuntu and found some issues on RPiOS.~~

Edit: passed locally on a RPi & ubuntu.

@stephendade What do think about the approach?

If you liked it anyway, I would ask you to wait a bit for the merge so I can do some new installs to test it better.

[stephendade]

Thanks for proposing this feature, it'll be quite useful.

A few notes:

1. I'd rather have the processing controlled within Rpanion-server, rather than an external systemd service. Take a look at the ./server/cloudUpload.js for an example
2. The user should be able to enable/disable the kml processing from a checkbox in the flight logs page
3. I note that pymavlink has a tlog->kml converter (https://github.com/ArduPilot/pymavlink/blob/master/tools/mavkml.py). Any reason you're using tlog->gpx->kmz instead of the mavkml tool?

Regarding items 1 and 2, I will try, but being JS, maybe something will come out based on monkey see monkey do.

Regarding item 3: It was on purpose because there is a desire to make some other formats available in the future. For example, Gpsbabel already handles Geojson. Geojson, it would be simple to quickly plot the flight log in the browser.

What do you think?

[brunoolivieri]

@stephendade I guess I did it as you requested.

Please, let us maintain as WIP until I use it in a quad for some extra tests...

[brunoolivieri]

This is good to go. I did some flyghts and work well.

@stephendade Would you merge? Should I rebase?

PS: Lessons learned: The RPi clock can cause a race condition on lognames...

[stephendade]

Great! I'll do a review, but generally looks OK.

[stephendade]

Hi @brunoolivieri - I can't see the changes you made. Did you push them to your branch?

[brunoolivieri]

Hi @stephendade, I think I pushed correctly now. I guess I addressed your requests.

Please, could you review that?

[brunoolivieri]

I kinda failed in rebase that

[stephendade]

Ok, I've had a look through it and it almost looks good to go. You'll need to remove the "merge commit" and then do a rebase - so that your branch is synced up with the latest changes in master.

Happy to help with this if needed.

[stephendade]

OK, to fix up the merge commit do:

git reset --soft HEAD~8
git commit -a
git pull --rebase upstream master

Fix up any merge conflicts, then re-commit

[brunoolivieri]

Rebased! Tks! :)

[stephendade]

Merged!
