feat: introduce a non-blocking keygen 

* ui can be used normally even while keygen is running; the only thing
  that the program will refuse to do is spin up another instance of
  keygen, of which the user will kindly be informed
* this required some async-await fiddling and running genprimes_handler
  as a Task
