SphericalPanorama and GeoTIFFSource: small gaps visible when zooming

Summary

It seems like the stitching problem on panos is back, I have no problem with StaticImageSource, but with GeotiffSource while using EPSG:4326. I saw that there was CoordinateSystem.equirectangular but I can't import CoordinateSystem on the 0.43.2 version of giro3d as the file doesn't exist when the library is pulled from npm. The gape is way smaller than the first time it happened but it's still visible if you zoom enough

Steps to reproduce

1. Create a spherical Panorama
2. Add a GeotiffSource with crs: "EPSG:4326" or 2. use CoordinateSystem.equirectangular with the right import

If this can help in anyway this is how we create GeoTIFF layers:

    if (url.endsWith('.tif')) {
        source = new GeoTIFFSource({
            url: url,
            crs: epsg, // epsg = "EPSG:4326"
        });
    } 

Expected behaviour

no visible gape with GeotiffSource

Actual behaviour

visible gape with GeotiffSource
