Update visualization input to streamline connection to extraction output

[cmcouto-silva]

As described in issue #13, the current implementation doesn't connect seamlessly with SQLDeps extraction.

This PR solves this issue so that users can generate interactive graphs with ease:

from sqldeps.llm_parsers import create_extractor
from sqldeps.visualization import visualize_sql_dependencies

# Create an interactive network graph from multiple SQL files
extractor = create_extractor()
sql_profiles = extractor.extract_from_folder("path/to/folder", recursive=False)

# Generate an interactive visualization (saving output to an HTML file)
figure = visualize_sql_dependencies(sql_profiles, output_path="dependencies.html")

# Show figure on IDE
figure.show()

Show buttons by default, since it's a pretty cool feature for end users :)
