Replace PNG network logos with vector drawables

[patkan]

The transport network logos in the picker have different sizes. I think they should all be the same size.
How can this be accomplished? Simply rescaling the svg and then putting it through the exporter? I tried it, but it seemed to not always work.
And if they should all be the same size, then how large should they be?

SVG logos should all have 64dpx64dp. If they don't have that, this can easily be changed in their XML file.

I suspect this issue to be really about updating the remaining raster graphics to SVG. Could that be it? If so, @nautilusx and @vinzv had started with that, but I haven't seen more PRs from them so far.

And now I understand why some networks have magically a logo even when I could not find it. Yep, the problem is that the "false" sized networks PNGs are.

I updated the title of this issue to reflect that it is really about changing the graphics to vector drawables. The homepage has information on how to do that here: https://transportr.grobox.de/#contribute

It's on my to-do-list for October. I will create/update all other logos. Germany and Austria are done.

On my way through the transport networks I found the new logo for TFI in Ireland and created it. It's not perfect but if you start working on the logos I could give you this one. Alternatively feel free to pull it in, I have it in my fork of this repo.

@patkan Please feel free to open a PR just for one logo if you have it already. What's done is done.
