🔢 Miscellaneous

• Update READMEs and package.json (#891) by @WoLewicki and @kacperkapusciak
• Add react-native-reanimated v2 to TestsExample (#898) by @WoLewicki
• Add branded header image to README (#917) by @jkadamczyk
• Bump react-native to 0.64.1 (#916) @kacperkapusciak
• Remove check for screens enabled in native stack (#922) by @WoLewicki
• Add headerShown check in modals in Example (#924) by @kacperkapusciak

Be aware that #821 may be considered a BREAKING CHANGE since it slightly changes how headerShown prop works.
We discourage changing headerShown prop directly in the navigator's screenOptions. We suggest changing it for a specific screen in options prop. Keep in mind that headers in modals aren't shown by default.
