Issue:
Implement ITK recipe
Specify library name and version:  **itk/4.13.2**

- [X] I've read the [guidelines](https://github.com/conan-io/conan-center-index/wiki#how-to-submit-a-pull-request) for contributing.
- [X] I've followed the [PEP8](https://www.python.org/dev/peps/pep-0008/) style guides for Python code in the recipes.
- [X] I've used the [latest](https://github.com/conan-io/conan/releases/latest) Conan client version.
- [X] I've tried at least one configuration locally with the [conan-center hook](https://github.com/conan-io/hooks.git) activated.
