Typescript errors on import

[Stevenlee731]

Hi! I'm receiving compile errors when im importing Reparentable. This is on a fresh new Create React App with Typescript.

`TypeScript error in /Users/node_modules/react-reparenting/dist/types/core/addChild.d.ts(1,13):
'=' expected. TS1005

1 | import type { Fiber } from 'react-reconciler';
| ^
2 | /**
3 | * Add a child fiber in a parent fiber and return the index in which it is added.
4 | * The position can be chosen by providing a key (string) or by providing an index (number).`

Deleted the tsconfig file and everything started to work.

updating typescript from "~3.7.2" to "^3.9.3" fixed the issue for me.

This is likely related to typescript-eslint/typescript-eslint#1436, however we might consider adding < 3.8 TypeScript support
