correct usage of lichess api

That's critical...and very very stupid.... I tried to profile the software and i got:

         1242615 function calls (1228231 primitive calls) in 15.201 seconds

       57    0.537    0.009    0.537    0.009 {method 'load_verify_locations' of '_ssl._SSLContext' objects}

That's because I've opened and closed the socket at each call to the lichess api....that's crazy and super stupid. Just fix it !
