Replaces #13365
As noted in #13609 (comment) the example in #13365 suffers noticeably from tile edge effects and also produces poor results on mobile devices due to #13500. The former is overcome by using Terrarium tiles with gutter, and the latter by creating, where supported, Float32 data tiles from the image tiles.
I found the Nextzen tile source with gutter to be unreliable so instead dynamically created one buffered tile from nine adjacent tiles loaded from AWS. https://deploy-preview-13647--ol-site.netlify.app/en/latest/examples/contour-interpolation.html
