Implement OSFS.copy using sendfile or shutil.copy (#216)

* Use `shutil.copy2` as the backend implementation of `fs.osfs.OSFS.copy`

* Add support for `pyfastcopy` extra in `fs.osfs` if installed

* Include backport of `shutil.copyfile` using `sendfile` to `fs.osfs`

* Add tests to check for unsupported `sendfile` in `tests.test_osfs`

* Refactor `OSFS.copy` into a single method for both implementations

* Add test for line not covered in `OSFS.copy`

* Use `os.fstat` in `OSFS.copy` to get the size for `sendfile`
