Type definition for RouterState too loose ?

[AndreiIl]

Hello!

Firstly, thank you for creating and sharing this package, I've been looking for a replacement for connected-react-router and this package seems to be the best fit.

While in the process of swapping out code, I noticed that I get a lot of TS errors when I use RouterState related fields, predominantly location, which I wasn't when using connected-react-router. Checked their type definition and it seems that the location field for their RootState type isn't optional: https://github.com/supasate/connected-react-router/blob/master/index.d.ts#L34

I am wondering why & when location can be null/ undefined ? Adding type guards everywhere seems like a hacky way of addressing the issue.

Thanks in advance.
