Set value to `atomFamily` from `get` method of `selectorFamily`.

[LvChengbin]

import { atomFamily, selectorFamily } from 'recoil';

export const tagState = atomFamily( { ... } )

export const tagListState = selectorFamily( {
    key : 'list',
    get( options ) {
        return async () => {
            const list = await getList();
            list.forEach( ( item ) => {
                // I want to set data here.
                set( tagState( item.id ), item );
            } );

            return list;
        };
    }
} );

As the code above, I want to store each tag into an atom after loading them as an array from remote server. What is the best way for doing this?
