Rust API missing Binary Modification Documentation

[a1rb0rn3]

Describe the bug
The rust API lacks documentation on how it can be utilized to modify or write PE files: e.g. lief::pe::Section to modify a binary by adding custom sections. I am not sure whether this is simply not documented or not implemented yet.

To Reproduce
I didn't get it to work on rust but for C++ the implementation would be (as described in the docs https://lief.re/doc/latest/formats/pe/index.html):

std::unique_ptr<LIEF::PE::Binary> pe;

LIEF::PE::Section section(".hello");
section.content = std::vector<uint8_t>(0x100, 0xCC);
pe->add_section(section);

pe->write("new.exe");

Expected behavior
A simple way to construct a new lief::pe:Section or a clear and concise description on how to utilize the Rust API (including the lief_ffi package???) to modify and write PE files by adding new sections.

I would expect something similar to this:

let mut pe: lief::pe::Binary;

let mut section = lief::pe::Section::new(".hello");
section.content = vec![0xCC; 0x100];
pe.add_section(section);

pe.write("new.exe");

Environment (please complete the following information):

• System and Version : Ubuntu 22.04
• Target format: PE
• LIEF version: 0.15.1

Additional context
The Problem could still be layer 8 as I'm relatively new to rust :D
