peerDependencies causing package management errors for more recent versions on react-native

Error as reported by yarn

yarn check v1.3.2
error "react-native-custom-keyboard#react-native@^0.29.0" doesn't satisfy found match of "react-native@0.50.3"

Error as reported by npm

npm ls
npm ERR! peer dep missing: react-native@^0.29.0, required by react-native-custom-keyboard@1.0.4

  "peerDependencies": {
    "react-native": "^0.29.0"
  }

Unfortunately it seems that the caret doesn't work as one might expect with 0.X.X packages.
As it stands, this package declares it only works with the following react-native versions:

• 0.29.0
• 0.29.1
• 0.29.2

Mind updating to more accurately reflect which versions of react-native this plugin will work with?

If you want to keep it pre 1.0: >=0.29.0 <1.0
