fix: project build error with new haskus-utils-variant version

Browse Source 
* New haskus-utils-variant version 3.3 now includes the function
  "throwSomeE", which was now causing a compile error, since
  we have a function of the same name in our code.

* The function imported from the package and our own version clashed.

* Solution was to conditionally include our shim when haskus-utils-variant
  version < 3.3
