Hook up `offset` to enable starting export from a particular position

[sweep-ai[bot]]

Description

This PR addresses the issue #4 by implementing the ability to start an export from a particular position using the offset parameter.

Summary of Changes

• Modified index.ts to parse the offset from the command line arguments and pass it to the getModuleData function.
• Updated getModuleData.ts to remove the hardcoded offset and use the one passed in from index.ts.

Please review and merge these changes. Thank you!

Fixes #4.
