Add React 17 to the compatibility list

[kirianguiller]

Hello, thanks a lot for your amazing library :)

My team and me are using react 17, but atm, for this library, only react 16 is "supported". So when doing npm install, we get an incompatibility error that can be fixed with adding the parameter --legacy-peer-deps.

As we saw no problem in the library, maybe after checking, we could add React 17 to the versions of react that are supported by react-calendar-heatmap ?

Thanks a lot !

I created a forked version of it. I plan to maintain this package
you can use this

Sorry this is ultra late; I've added React 17 and 18 to the peerDependencies in v1.9.0. Let me know if there's still an issue.
