Ability to specify extension when the extension is not part of the url

Hi, I'm trying to render .gltf objects from ipfs, but the engine can't process the file. Although it can process exactly the same file from another source:
E.g:
it works correctly here: https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Embedded/DamagedHelmet.gltf
it doesn't work here: https://ipfs.io/ipfs/QmVzbVRXNr46NRhkjifUjxGj9KcfXUiMYvHTxYcW2h74A4
But when I get those links from the browser, both are exactly the same.

P.S: I don't think this is a CORS issue

Well I figured it out, it is an extension problem, the engine does not know how to read my file since the filename/extension is not in the URL, to solve this I hardcoded "gltf" as a default value when it can't infer the extension, but it could be great to somehow have the option for sending the extension before rendering the object

Hello @kovacsv, for production use cases, it's not always possible to have the extension in the download file URL. I have a project where we're trying to use this library and this is a major obstacle. We can have another variant for LoadModelFromUrl where we can specify the extension alongside the model URL. If possible, please look into this with a higher priority. Thank you.

From the next release it will be possible to provide file names along with urls:

let inputFiles = [
    new OV.InputFile ('hundred_cubes.obj', OV.FileSource.Url, '../../test/testfiles/obj/hundred_cubes_noext_obj'),
    new OV.InputFile ('hundred_cubes.mtl', OV.FileSource.Url, '../../test/testfiles/obj/hundred_cubes_noext_mtl')
];
viewer.LoadModelFromInputFiles (inputFiles);
