🐛 export Signer and SignPdfError from utils

Consumers of the library may want to implement their own Signer or even catch and make
assertions of errors. Exposing the classes from utils through this library means that
consumers don't have to manually require the sub-package themselves, which helps avoid
dependency resolution issues that can sometimes happen in npm when root projects and
dependencies have slightly mis-matched version requirements.
