crane: pull hangs (container v0.21.6)

[lqb]

Describe the bug

Pulling hangs for some images in v0.21.6 while v0.21.4 works

To Reproduce

This hangs:

time docker run --rm gcr.io/go-containerregistry/crane:v0.21.6 pull gcr.io/go-containerregistry/crane/debug:v0.21.6 /tmp/pull

The old version worked:

time docker run --rm gcr.io/go-containerregistry/crane:v0.21.4 pull gcr.io/go-containerregistry/crane/debug:v0.21.6 /tmp/pull

Result from time:

real    0m13.023s
user    0m0.022s
sys     0m0.05

Expected behavior

The download finishes as in v0.21.4

Additional context

docker run --rm gcr.io/go-containerregistry/crane/debug:v0.21.6 version
53f7e39

The download worked in v0.21.5, too
