Version 1.9.0

Changelog

• Added histogram plotting fallback logic for non-TTR input. In PlotData._construct_plot_data, if the TTR pipeline fails or the input is not a valid TTR, the code uses a uniform-width histogram approach, ensuring more robust and meaningful binning for arbitrary Dirac deltas.
• Removed all from __future__ import annotations statements.
• Updated some typing annotations.
• Updated dependencies.
