Add thorough `launch.json` for basic debugging

[peterhessey]

🚀 Feature

Add a launch.json file that contains a number of common setups used for debugging IE-DL.

Motivation

Debugging IE-DL locally currently requires the user manually setting up a debug config in their IDE of choice. As we recommend and VS Code for developing this toolkit it makes sense to include a debug config to reduce repeated efforts when debugging, as currently devs have to set it up manually each time. Furthermore, for those who aren't as familiar with debugging configs, the launch.json file will provide a useful tempalte from which one can more easily create new debugging configurations.
