Cannot open .glb file after conversion from .gltf

[quipo]

Getting EOF error when opening a .glb file converted from .gltf using gltf.SaveBinary().

Sample input .gltf file: https://github.com/qmuntal/gltf/files/9627951/simple.gltf.txt

Sample script:

import (
    "log"

    "github.com/qmuntal/gltf"
)

func main() {
    const simpleGltf = "simple.gltf"
    const outputGlb = "simple.glb"

    srcDoc, err := gltf.Open(simpleGltf)
    if nil != err {
        log.Fatal(err)
    }
    err = gltf.SaveBinary(srcDoc, outputGlb)
    if nil != err {
        log.Fatal(err)
    }

    tgtDoc, err2 := gltf.Open(outputGlb)
    if nil != err2 {
        log.Fatal(err2)
    }
    log.Println("SUCCESS!")
    log.Printf("DEBUG: %#v", tgtDoc)
}

NB: error seen using latest version of gltf package (v.0.22.1), but not using an older version (v.0.18.3). The output files slightly differ, it looks like the old version of the package was adding some nil "padding" at the end.
