ConvenientPatch#hunks documentation is incorrect

[JC3]

The documentation at https://www.nodegit.org/api/convenient_patch/#hunks indicates that the return of hunks is an Array<ConvenientHunk>.

However, there is no such type as ConvenientHunk. It is not clear what hunks() actually returns.

There is ConvenientHunk, the documentation for it is missing tough. see #1939

I managed to work out the relevant API by trial&error and inspecting the javascript objects.

See here where I query nodegit to return the diffs of a commit and fill them in my own down datastructures:
