There is no way for nydusify to specify ignoreArch?

How is it going to be used? Please add an example in the docs.

Updated comment. No way to specify. For a single manifest image, it's an automatic behavior to ignore the image arch for ease of use, attempt to continue converting, and give a warning message. For the manifest list, nydusify selects host specified arch to convert, but the user still can specify an interesting platform (by --platform), the ultimate goal is that nydusify/nydus-image can convert any arch's image on any arch's host.

For a single manifest image, we just ignore the arch, so that allowing to do a default conversion on a different arch's host, for example converting an arm64 image on an amd64 host. Signed-off-by: Yan Song <imeoer@linux.alibaba.com>

The same error message should be returned if no ignoreArch.
