Correct way of importing pouchDB with Angular

### Issue
I am trying to use Angular with pouchDB but i have some trouble importing pouchDB on component.
If i import with:
`
import PouchDB from 'pouchdb';
`
It works but show an error on VsCode:
`
Module '"MYPATH/angular-pouchdb/node_modules/@types/pouchdb/index"' can only be default-imported using the 'allowSyntheticDefaultImports' flagts(1259)
index.d.ts(24, 1): This module is declared with 'export =', and can only be used with a default import when using the 'allowSyntheticDefaultImports' flag.
`

I added the allowSyntheticDefaultImports flag like shown on docs: https://pouchdb.com/guides/setup-pouchdb.html#typescript

If i change the import to:
`
import * as PouchDB from 'pouchdb';
`
I get this error on console and project stops working:
`
pouchdb__WEBPACK_IMPORTED_MODULE_1__ is not a constructor
`
