Error with certain width/height and pixel ratio for svg images

[pathmapper]

Steps to reproduce:

Use the CLI with:

{"id": "green", "url": "{base_url}/images/green.svg", "width": 200, "height": 200},

http://localhost:8080/acme/[email protected]

Error: Expected number between 1 and 2400 for density but received 2880 of type number

With
https://cdn.jsdelivr.net/gh/maputnik/osm-liberty@gh-pages/svgs/svgs_iconset/airport_11.svg
this happens with "width": 200, "height": 200 and @3x.

So for more complex SVGs this seems to happen at a lower width/height and pixel ratio.

It's kind of an odd one, because the density is based on the width/height of the input SVG. Which is defined by the width/height attributes.

<svg width="20" height="20">
  <!-- ... -->
</svg>

So sharp seems to only allow a max density of 2400, however if you where to change the the SVG to width/height 200 instead

<svg width="200" height="200">
  <!-- ... -->
</svg>

Then you wouldn't need such a high density. If a viewBox is present on the SVG as it is in the case of green.svg then it'd 'just work' however I believe if it's missing a viewBox.... hmm I'm not actually sure what happens if we're missing a viewBox attribute would need to do some tests.
