KTX support in WASM builds

[MAG-AdrianMeredith]

Hi Bevy-ites!
I noted that ktx textures aren't currently supported in wasm builds (at least by default). Is there something extra required to support this? I would like it to just work if at all possible (so it can be both native and wasm). If its not currently possible to "just work" I presume its not too difficult to use the existing ktx javascript/wasm library to decode them beforehand. Is there then an easy way to pass in the decoded image to bevy?

Thanks everyone
