Treat qrcode as dependency rather than peerDependency

[colgin]

In version 1.x, qrcode is dependency, but it changed now, it is peerDependency now. I'm really puzzled about what makes this change.
In my opinion, users don't need to install qrcode manually if qrcode is treated as dependency.

For a peer dependency, users can choose the exact version of qrcode as they need, just like Vue components don't list vue package as a dependency but as a peer dependency.

how about use overrides and resolutions properties to replace peer dependency?
