Provider fails due to missing dependency

[plumdog]

With 1.0.2, get an error like:

16:21:30 | CREATE_FAILED        | Custom::SesSmtpCredentials | Credentials/Resource/Default
Failed to create resource. Error: Cannot find module 'strftime'
Require stack:
- /var/task/index.js
- /var/runtime/UserFunction.js
- /var/runtime/index.js

Inspection of the installed files shows:

$ ls node_modules/ses-smtp-credentials-cdk/provider
index.ts  jest.config.js  lib  package.json  package-lock.json  tsconfig.json

So something has gone a bit awry in the build and publish steps, because there's no node_modules/ there, which I would expect to find.

I also tried importing like:

import { SesSmtpCredentials } from 'ses-smtp-credentials-cdk/lib';

which gets the same error, and:

$ ls node_modules/ses-smtp-credentials-cdk/lib/provider
index.js

Intended approach: use CDK's NodejsFunction.
