React import style causes issues with build

I'm importing use-latest through react-textarea-autosize in a React library that gets built with rollup. The importing package (pkg-a) works and builds fine but packages that import that package (pkg-b) are unable to run and crash with the error:

TypeError: Cannot read property 'default' of undefined

> 10 |  */"production"!==process.env.NODE_ENV&&function(){var e=t,n=Symbol.for("react.element"),r=Symbol.for("react.portal"),o=Symbol.for("react.fragment"),i=Symbol.for("react.strict_mode"),a=Symbol.for("react.profiler") [...]
     |                                                          ^

After adding react-textarea-autosize, the beginning of the built dist file changes from:

import e,{Component as t}from"react";

to:

import*as e from"react";import t,{Component as n,useLayoutEffect as r,useEffect as o,useRef as i,useCallback as a,forwardRef as s,createElement as l}from"react";

I've narrowed the issue down to this package (use-latest), and specifically the React import line:

import * as React from 'react'

The issue is resolved by changing the line to either:

import React from 'react'

or:

import { useRef } from 'react'

I believe the latter change is more in the style of your packages.

I will submit a PR shortly.
