Update cran-comments, closes #58

cran-comments.md

-This is a bugfix update. It fixes some failing tests on macos and changes the maintainer's email address. I recently learned that my old address (sebastian.henz@ufz.de) is going to get deactivated in a few months. To ensure long-term maintainability of the package I changed the address to one that will remain active for the foreseeable future (many years). I have sent a confirmation from the old address to cran-submissions@R-project.org.

 ## R CMD check results
-There were no errors or warnings.
-There were 3 notes:
-
-* checking for future file timestamps ... NOTE
-  unable to verify current time
-
-I believe this is not caused by my package but instead by how R checks 
-timestamps, which seems to be broken at the moment.
-
-* checking CRAN incoming feasibility ... NOTE
-  Maintainer: 'Sebastian Henz <bastihz.dev@posteo.de>'
-
-I changed the maintainer e-mail address, see comment above.

-         	    when a fatal SSL/TLS alert is received (e.g. handshake failed).
-
-This note is from R-hub for Windows Server 2008. I don't know what to do about that because the new email address is definitely valid and working.
+No errors or warnings.
