Missing lodash.merge dependency in azure-iothub npm package version 1.16.3

Context

• OS and version used: Windows (app service plan on Azure)
• Node.js version: 16.20.1
• npm version: 8.19.4

Description of the issue

We are running an Azure Function on an app service plan that is running on an app service plan. The function runs into the following error:

Exception: Worker was unable to load function scheduleRequestHandler: 'Cannot find module 'lodash.merge'
Require stack:
- C:\home\site\wwwroot\node_modules\azure-iothub\dist\common-amqp\amqp.js
- C:\home\site\wwwroot\node_modules\azure-iothub\dist\amqp.js
- C:\home\site\wwwroot\node_modules\azure-iothub\dist\client.js
- C:\home\site\wwwroot\node_modules\azure-iothub\iothub.js
- C:\home\site\wwwroot\node_modules\@enecoiot\edge-command-handler\index.js

- C:\Program Files (x86)\SiteExtensions\Functions\4.21.3\workers\node\dist\src\nodejsWorker.js'

The problem seems pretty clear. Indeed, I can see that in version 1.16.3 an import of lodash.merge was added to dist\common-amqp\amqp.js, but this module is not added as a dependency in package.json. There is a depenency to lodash, but that is not to lodash.merge which is a seperate package.
