Add reuse compliance

[AndyScherzinger]

Adding SPDX header.

@ChristophWurst while adding the headers I realized that:

• the wrapper is AGPL3+ https://github.com/nextcloud-libraries/kitinerary-bin/blob/main/src/BinaryAdapter.php#L8
• the lib is labelled LGPL3+ https://github.com/nextcloud-libraries/kitinerary-bin/blob/main/composer.json#L5
• the bin is LGPL2+ https://github.com/KDE/itinerary

So I would suggest to change the license of the php wrapper to AGPL3+ or LGPL3+

What do you think @arnebr @ChristophWurst @come-nc @kesselb @MCMic

[AndyScherzinger]

So this PR in itself is "fine" yet the license issue should be clarified/decided

[AndyScherzinger]

Alternatively the Lib moves to AGPL3+ which is also doable of course

I think I'd favor that because we use AGPLv3+ for Nextcloud and its apps too.

👍 for converting this project to AGPLv3+.

@arnebr @CarlSchwan @come-nc @kesselb @MCMic do you agree with this?

Everyone agreed so license should be changed to AGPLv3+ in a follow-up
