Several updates

- Change virtual resolution to 1280x720 - Change virtual to screen pixel ratio to 1:1 - Increase grid size to 420 - Make the mod capture only the window (and only the client area) - Increase STREAMING_CHUNK_TARGET, so that chunks don't unload after some frames - Add ingame warnings for wrong settings, and information how to fix these - Update README.md

 - `VIRTUAL_RESOLUTION_*` can be found inside `.../Noita/mods/noita-mapcap/files/magic_numbers.xml`
 - and `SCREEN_RESOLUTION_*` is the screen resolution you have set up in noita.

-If you have a resolution of `1366 x 768‎`, then you should change the `VIRTUAL_RESOLUTION_*` to `683 x 384`.
-Another solution would be to change the `CAPTURE_PIXEL_SIZE` to `1.423`, but then you would get blurry images.
-
 You can also change how much the tiles overlap by adjusting the `CAPTURE_GRID_SIZE` in `.../Noita/mods/noita-mapcap/files/capture.lua`. If you increase the grid size, you can capture more area per time. But on the other hand the stitcher may not be able to remove artifacts if the tiles don't overlap enough.
