Support for react-intl ^6.0.0

Good day

It would be great if this package supports react-intl ^6.0.0. Current support is for react-intl@"^2.2.2 || ^3.0.0 || ^4.0.0 || ^5.0.0"

Thanks and regards
Nate

Funny also how you have a dependency to react-redux ^8.0.0 internally, but in peer dependencies only until ^7.0.0 is supported... ;)
