Description

It would be nice to be able to read/write hacked PE files like Tiny PE file here or the one described in http://www.phreedom.org/research/tinype/

This test was working at some point during the development of PR #34 but I removed support for it.

The problem is that it requires to manage overlapping data (e.g. the content of PE Section stored in Dos Header) and it complicates significantly corner cases to handle when loading/writing. Not worth considering that I don't plan to hack around PE but manipulate/create fairly standard PE files.

Research direction

Start with the Tiny PE case in src/LibObjectFile.Tests/PE/PEReaderTests.cs, referenced by the issue, and review the overlapping-data behavior described there. Compare it with the support removed during PR #34; done means reading and writing the cited hacked PE files while preserving overlapping section data and corner cases.
