Add content to guide about writing interfaces + wrappers for libraries in other languages

[NickleDave]

Python is uniquely suited for writing wrappers + interface to libraries in other languages.

I think this is in scope for pyOpenSci since a lot of tools will be written in other languages and we want to provide access to them.
An example of a package we've already reviewed here would be pygmt.

It would be good if we could provide some guidance on good practices for doing this.

This came up in #21

Things to cover, this is a rough list that mainly reveals my ignorance 😕

• Ways to interface
  • CFFI
  • eval calls (not so good)
  • tools like SWIG
  • pybind11
  • rpy2
• Build tools, which I know we are thinking about anyway
  • Meson
  • scikit-build
  • dev.py
• example packages
  • pygmt

this would be an awesome topic for someone to tackle.
we have a single basic page here on this topic but i could see this becoming a longer section in the guide in the future. we might also link out to other resources. i'll mark this as a help-wanted issue as well.

i think this should be in this section

We should consider adding an overview of

• sckit-build as a backend (with hatch)
• meson-python with hatch (using @ucodery example package here
• potentially suggest scikit build tool that @henryiii has been working on (that seems to be a really good option right now)
• OPTIONALLY: highlight cibuildwheel also being developed by Henry!

This task could be broken into two

• Write more text explaining how these builds work - link to henry's content in the development guide
• Suggest scikit build as a recommendation
• Add a Scikit build example package using hatch!
