martin ui POC - WIP

[tomeronen]

This is a work in progress for a possible ui for martin. You currently can run it by running the martin server on port 3000 and then running the ui by going to martin-ui folder, and running

npm ci
npm run dev

@tomeronen, thanks so much for working on this! I tried it, but I couldn't actually get it to show the data from the selected layers - i used just start and just run in addition to the above commands (to run local test infrastructure). Note that this requires docker, rust compiler, and the just utility installed locally. I do everything on Linux, so other OS were not tested as thoroughly.

I started #1120 to capture the "grand vision" for the UI.

P.S. Just a suggestion - whenever creating a PR for any project, create a new branch on your fork, don't use main branch for that.
P.P.S. this describes the best way to contribute IMO:

going to open a series of small PR's to be more organised and so they will be reviewable
