Currently when I try to open a ZSTD compressed GeoTIFF I'm getting the following error:

"Error: Unknown compression method identifier: 50000
    at getDecoder (http://localhost:8091/dist/main.js:16498:11)

The list of supported decoders by geotiff.js at the moment can be found here:

geotiff.js/src/compression/index.js

Lines 20 to 29 in f15d770

addDecoder([undefined, 1], () => import('./raw.js').then((m) => m.default));
addDecoder(5, () => import('./lzw.js').then((m) => m.default));
addDecoder(6, () => {
throw new Error('old style JPEG compression is not supported.');
});
addDecoder(7, () => import('./jpeg.js').then((m) => m.default));

50000 is a reserved identifier for ZSTD: https://github.com/OSGeo/gdal/blob/301f31b9b74cd67edcdc555f7e7a58db87cbadb2/frmts/gtiff/gtiff.h#L117-L119
