Show compressed file content, like Understand does for the Java standard library

[robbycbennett]

Replicate:

1. Open the sample project TheAlgorithms
2. Open the file DataStructures/DynamicArray/DynamicArray.java
3. Go to the definition of Iterable
4. A file opens which VS Code doesn't find \Program Files\Java\jdk-17.0.2\lib\src.zip{java.base\java\lang\Iterable.java}

Possible fix:

• Add a URI handler into the language server which will unzip the file and show the contents as read-only
