verifyAllUsers() returns userID error for keys that contains image data

[martgil]

• OpenPGP.js version: "openpgp": "^5.8.0"
• Affected platform (Browser or Node.js version): Node.js (I haven't tried for the Browser version/dist)

Description:

During my testing, OpenPGP.js verifyAllUsers() fails to work and returns TypeError: Cannot read properties of null (reading 'userID') when parsing a public key/key pair that contains image data. eg image added with gpg's addphoto command.

File to use:
sample.pub.txt

Steps to reproduce:

const key = `$armored_key`;
const k = openpgp.readKey({armoredKey: key});
const vk = (await k).verifyAllUsers(k);
console.log(vk);

Hey 👋 Thanks for the report! Indeed it seems like this function doesn't take User Attributes into account. We'd welcome a PR to fix this :)

Thank you! I attempted to fix this issue on #1637 based on the original issue. I'd love to contribute to OpenPGP.js as much as I'd like but if the fix requires more in-depth javascript skills - It's sad to say but I'm not really good at JS.
