Feature Request: Filtering Programs

Hi, team. This tool is a great initiative!, I hope to see it evolving fast.

### Feature Request

Allow to filter programs from our Anchor.toml for x-ray'ing

Proposed approach:

"Only these specific programs":
```
anchorx-ray --include`program1` `program2`
```
"All my programs, but exclude these ones":
```
anchorx-ray --exclude `program1` `program2`
```

### Rationale

In large codebases, we may want to perform scoped x-rays instead of being forced to scan and visualize everything contained in the repository.

Start by locating the anchorx-ray CLI entry point and the code that reads Anchor.toml; the issue names no files or tests. Define completion as include selecting only the named programs and exclude omitting the named programs, while leaving other scans unchanged. Check the resulting CLI behavior against the proposed commands.
