nimterop-wrappers repo
(first discussed here https://gitter.im/nimgen/Lobby?at=5c4f81ebf04ef00644a0be7a)

* nimterop repo is what it is today (wrapping engine)
* nimterop-wrappers is another repo with 1 module per library wrapped; eg it would contain wrap_freeimage.nim which itself contains  needed (including cPlugin) to successfully wrap freeimage.h librarry
  * nimterop-wrappers grows over time, and is kept up to date with changes in nimterop as well as upstream library that is being wrapped
* client code that wants to user freeimage from nim just needs 1 line:
```nim
import wrap_freeimage
```
* higher level wrapper libraries could be either in nimterop-wrappers or in their own separate repo, that part is un-decided

## example
* closest existing example for a wrapper_foo.nim would be https://github.com/genotrance/nimterop/blob/master/tests/tsoloud.nim but we can come up with a more idiomatic example that could serve as model for other wrappers

## benefits
* nimterop-wrappers is expected to grow over time as more wrappers are added and it makes sense to split from `nimterop` for exact same reasons https://github.com/Homebrew/brew is split from https://github.com/Homebrew/homebrew-core
* keeping wrappers in 1 repo makes it much simpler to manage eg when upgrading to a more recent release of `nimterop`
* avoids boilerplate overhead of 1-repo-per-thin-wrapper as seen in https://github.com/kaushalmodi/nim-svdpi which contains really just 1 interesting file and a bunch of "boilerplate" github files ; less boilerpate means smaller barrier of entry to add wrappers /cc @kaushalmodi

## early candidates for nimterop-wrappers
* freeimage pending remaining bugs https://github.com/genotrance/nimterop/issues/74
* soloud https://github.com/jarikomppa/soloud since we already have https://github.com/genotrance/nimterop/blob/master/tests/tsoloud.nim
* math `<math.h>` https://github.com/genotrance/nimterop/blob/master/tests/tmath.nim 
* EGGX / ProCALL X11 Graphics library eg https://github.com/kaushalmodi/nim-eggx/blob/master/eggx.nimble
* libarchive https://github.com/libarchive/libarchive
* [kaushalmodi/nim-svdpi: Small wrapper for SystemVerilog DPI-C header svdpi.h](https://github.com/kaushalmodi/nim-svdpi)
* more generally: https://github.com/search?q=nimterop
