top-level styleSheetSerializer export erases toHaveStyleSheet TypeScript definition

[landisdesign]

The fix from issue #259 turned index.d.ts from a global file to a module. This erases visibility to the declare namespace jest code and visibility to toHaveStyleSheet. Because of this, TS projects fail to compile in development mode.

I fear a breaking change is required, to remove the export from top-level jest-styled-components and require users needing the serializer to get it from the source in jest-styled-components/serializer.

Any other suggestions? The separation works, because jest-styled-components/serializer can have its own index.d.ts file set up as a module. Anyone who took advantage of importing from the top-level module can change their code to import from the serializer subdirectory.

But it is a breaking change.

This change would also fix issue #291.

I have also this issue - I had to download the d.ts to my local code and point in tsconfig: "jest-styled-components": ["types/jest-styled-components.d.ts"] and remove the line: export declare const styleSheetSerializer: Exclude<Plugin, NewPlugin>; in order for it to work
