Added Flitsmeister

[robinbonnes]

This PR adds support for the Flitsmeister app.

[frankvollebregt]

Hi! I noticed that it doesn't work on iOS devices (it opens the app without starting navigation). Also, this PR is now outdated. I made a PR to your fork to add Truckmeister and update the package. Please have a look: https://github.com/robinbonnes/map_launcher/pull/1

We do need to figure out how to use the URL scheme on iOS, though.

[frankvollebregt]

I just heard back from Flitsmeister, and they stated the following:

1. iOS support for passing a location is not available and not currently planned
2. Android support happens to work, but was never built into the app consciously

For now, we can set these packages as "Android only" and proceed with merging. @robinbonnes can you take a look at my PR over in your fork?

Otherwise, I'll create my own PR with your commits instead.

@frankvollebregt can you create a new pr with those and your changes? I'll make sure to mention both of you in the changelog

[robinbonnes]

Hey Frank, Thanks for also adding Truckmeister! I've just merged your PR, ofcourse you are always free to make your own PR.

[mattermoran]

hey @robinbonnes
that's awesome, could you then also make sure there's no merge conflicts? then I can merge this pr

[robinbonnes]

Hey @mattermoran,

I've just fixed those.

[frankvollebregt]

We should clearly tell that iOS is not supported for these two (at the time). We can open the app, but can't start navigation

[mattermoran]

@robinbonnes fantastic, thanks!

@frankvollebregt if it can only open the app itself on iOS I think it's pretty useless and we can just remove support for it and make it android only (just like some other maps)

Will clean up tomorrow and make a release.

[mattermoran]

Well it was a very long tomorrow but it is now available in v3 :)
