Describe the bug

Blank basemap-only page when attempting to load ZSTD compressed cloud optimized geotiffs. Browser dev console says "Error: Unknown compression method identifier: 50000".

Sample image and gdalinfo report attached. Excerpt:

To Reproduce

1. Put attached html and sample-cog.tif somewhere appropriate, edit paths as needed.
2. Load page
3. Open web developer tools (F12)
4. Switch to console

Hi, @maphew . Thank you for reporting this! Unfortunately, I'm a bit stretched for time at the moment (some projects wrapping up at the end of the calendar year). I think the issue is that georaster is using an older version of geotiff.js, but unfortunately rebuilding the georaster package with this new version has had some issues (different build tools used by georaster expecting conflicting versions of nodejs).

The good news is there is light at the end of the tunnel. I've also been working on a major re-write of georaster-layer-for-leaflet and georaster, which should solve these types of issues.

Just in case it works, I'd also recommend trying the newest pre-release version of georaster-layer-for-leaflet by
npm install georaster-layer-for-leaflet@next

@maphew , would it be alright with you if I added this geotiff to this test data repo? (https://github.com/geotiff/test-data)

It's baseline test data that's used in a whole range of projects in the JS geotiff ecosystem and would have more libraries making sure it works with that geotiff.

Thanks for having a look, and yes you can use the image for the test data repo. I totally understand making it through dance of time, attention, and worthy projects is not easy!
