A well ballanced bike that is in good condition will compensate for crosswinds pretty much on its own. This is just physics and geometry. Except as needed to stay in your lane, it's best to just relaxe and let the bike deal with wind gusts because it will react quicker and more precisely than you can.
It does help if you are extra careful about making sure the tire pressure is correct when it's windy, and don't load a lot of stuff on the bike. That's why, when traveling, I carry what tools I think I might need, maybe 4 days worth of clothes, and little else.
