Add support for PE

[xoofx]

Draft PR that brings support PE read/write.

The code is far from complete but it is starting to get a good chunk of functionalities.

What is missing:

• Delay Import Directory
• Bound Import Directory
• Debug Directory
• Printing PE
• Writing PE
• Validating PE
• Manual PE Creation
• Add PE checksum calculation
• Add PE signing
• Basic Unit tests
• Class diagram PE
• Basic Documentation PE
• Advanced Documentation PE

The PR is also bringing significant refactoring of the base Object (e.g ObjectFileNode to ObjectElement/ObjectFileElement), so this PR comes with lots of breaking changes.

This PR is not meant to be reviewed, too big! 😅

@filipnavara hey, I saw that you saw. 😅 I don't know if you will have any use of this, but it is completed and I'm really happy with the results and the API. 🎉

I may have a use for it in some side projects. Lots of plans for next year and little time so let’s see what makes the cut :) Congratulations on the big release!

One thing that I'm going to investigate in the coming days, while it's still fresh in mind, is how I can reinject in the ELF part some of the things I have revisited while developing PE. As I folded the PE Directories into PE Sections, it made the design much simpler and versatile to support any kind of layout, and to author it easily while keeping an API that is easy to use.

The ElfObjectFile design has a relatively strict separation between sections and segments, but I could definitely see that sections could be designed in a similar way I designed PE Directory. It might help with some ELF oddities that ElfObjectFile had trouble to manage, and it could make it simpler to author in the end. I will open a PR if I have found improvements. Let's see. 🤞
