Issue with Malformed PE Files

[IneeddHelp]

When run on files received from dd-run with malware-bazaar, LIEF is unable to parse the samples, returning None after calling lief::Binary::from. However, when tested on malware I got from a GitHub repo, it runs fine. 2 parts to this issue

1. Why? I assume because of a malformed DOS header, in which case, it should be safe to assume the file is malicious (I think). But I am not completely sure. Or is it possibly something weird or unique about the sample source?

2. How should this be handled? Should the file be skipped? Should the row say something about it in the csv? Up for discussion
