Direction for PE file support

To add support for PE files there are a few different approaches that can be used:

- Import a submodule for [LIEF](https://github.com/lief-project/LIEF) (this also supports other files, maybe all parsers could leverage this?)
- Import a submodule for a parser like [pe-parse](https://github.com/trailofbits/pe-parse) which is more of an iterating parser, and specialized for PE files
- Grab some headers / classes from LLVM and write something along the lines of [COFFDump](https://github.com/llvm/llvm-project/blob/master/llvm/tools/llvm-objdump/COFFDump.cpp)
- Grab only the [PE headers](https://github.com/llvm/llvm-project/blob/master/llvm/include/llvm/BinaryFormat/COFF.h) from LLVM and write a complete custom parser
- Other (please specify)

What would be the preferred way of moving forward?
