Chunk index calculation is wrong

[czunker]

Describe the bug
With the changes introduced with #1346, I think this code is no longer correct:
https://github.com/mondoohq/cnquery/blob/main/llx/code.go#L104-L107

This is how the values look like when called for some sshd.config fields:

When the binding/ref is directly passed to Chunk() it results in a index out of range panic.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Select '....'
3. Scroll down to '....'
4. Note the error

Expected behavior
The func should return a chunk and not panic.

its not clear to me why that is considered wrong. It could be that we don't subtract one from it somewhere when accessing the chunk. Or it could be we access the wrong block. Is there some repro steps of a panic you can provide me.
