PPF-1210: PdfWrapper crashes with any corrupted/unexpected widgets

[alvin-r]

Version

PyPDFForm=3.6.1

Issue Description

We use PyPDFForm with a large variety of PDFs - sometimes there's one corrupted/faulty widget in a PDF, that causes the Wrapper to crash. We should warn instead of error out when building widgets to prevent this from happening.

Code Snippet

Will update when I find specific non-customer examples that I'm able to share - but this is a generic issue with a long-tail of errors we're seeing in prod

Please stop creating PRs that simply wraps (potentially) problematic logics around a try catch block. If certain logics fail, they need to be fixed. And to do that actual PDF samples and code snippets are both needed.
