      Type 'typeof assert' has no call signatures.

It goes on for a while, for the other assert calls in node-opcua-crypto.

I tried the following in my project:

import * as assert from 'assert'; // does not work
assert('test' === 'test');

import assert from 'assert'; // works
assert('test' === 'test');
