Pakcage cl is deprecated

[santoshs]

I get this warning with native-comp emacs. But I believe this gets printed with vanilla emacs too.

Warning (comp): gh-common.el:30:13: Warning: Package cl is deprecated

also other warnings related to defmethod. Replacing cl with cl-lib and defmethod with cl-defmethod gets rid of most of the warnings expect a few which is listed below.

Not an elisp expert, fixing those was not straight forward.

Package is now completely broken after eieio-compat was moved to obsolete in Emacs 29 master.

Is this not fixed by #110
