(#24000) Add nifti_clib

* working recipe, shared not working though

* fixed shared build

* fixed system libs and added fslio option

* added license, removed comments and disabled tests

* fixed homepage and removed unused stuff

* incorperated requested changes

* forgot one change...

* added msvc shared being unsupported to validate

* Force static-library for Windows

* Revert "Force static-library for Windows"

This reverts commit d23de31.

* Update recipes/nifti_clib/all/conanfile.py
