Improve tile plot figure

[JeanMainguy]

This PR introduces several improvements to the tile plot figure:

• Gene Names in Hover Text: Gene names are now included in the hover text for tile plot boxes, as requested in #251.
• Metadata in Hover Text: Metadata can be added to the hover text using the --add_metadata argument.
• Dendrogram Addition: A dendrogram can now be displayed on the x-axis with the --add_dendrogram argument, addressing the suggestion in #81.
• Updated Color Bar: The color bar has been updated to display discrete values (absence, presence, multicopy) instead of a continuous scale.
• New Legend: A legend for partition information has been added to improve graph clarity.

Technical Details:

• Refactoring: The create_tile_plot function has undergo a complete refactoring.
• Dendrogram Generation: The dendrogram is now generated using plotly.figure_factory.create_dendrogram, removing the need for the previous SciPy function.
• Color Management: The Colorlover package has been replaced by fixed green colors, thus removing Colorlover as a dependency.

The tile plot documentation has been updated to take into account these changes.
