Replace UUID with ULID

[matrixik]

Is your feature request related to a problem? Please describe.
Replace UUID with ULID so exported names can be sorted lexicographically.

Describe the solution you'd like
It would fix people complains about wrong order of exported files (like #512 (comment)) and still provide unique identifier for tracks.

Describe alternatives you've considered
KSUID (more info: https://segment.com/blog/a-brief-history-of-the-uuid/). Differences to ULID: segmentio/ksuid#8.

If those are binary compatible and solve a problem - why not.

Some things to consider:

• Gadgetbridge also needs to be changed as they nowadays generate opentracks:trackid as well.
• opentracks:trackid in the export/imports is required to be backward compatible

And I am (personally) not a fan of adding external dependencies to OpenTracks as it complicates long-term maintenance.
So, far we managed to just use Androidx.

Let us know how you decide to proceed @dennisguse , so we can follow as necessary.

@vanous Not my problem - if somebody wants it, they have to built it.
Being backward compatible will be kind of painful though.
🤷‍♂️

@vanous Thanks ;)

Does not seem that important.
