Pull request overview

This PR refactors code organization and enhances functionality by moving the format_plot_regions function to a more appropriate module, expanding unit detection capabilities, and adding improved handling for optional variables in flux data processing.

• Moved format_plot_regions from flux_timeseries.py to regions.py for better code organization
• Enhanced get_posterior_unit (renamed to get_unit) to support additional variable types including prior variables
• Added conditional checks for optional posterior variables and improved error handling for missing data_dir when plotting inventory data

File	Description
tests/utils/test_format_region.py	New test file for the relocated format_plot_regions function with tests for default behavior, error cases, and dataset extraction
tests/test_plots.py	Added tests for plot_country_flux including default behavior and validation that data_dir is required when plotting inventory
fluxy/plots/flux_timeseries.py	Updated imports, renamed and enhanced get_unit function, improved axes handling, added data_dir validation, and conditional posterior plotting
fluxy/operators/regions.py	Added format_plot_regions function from flux_timeseries module, enhanced _extract_region_flux_sector to handle optional prior/posterior variables, improved Path handling

• If ds_all is an empty dictionary, set.intersection with no arguments will raise a TypeError. Consider adding a check for empty ds_all or handling this edge case explicitly.
  fluxy/operators/regions.py:203
• Extra whitespace after variable: there are two spaces between variable and =. Should be variable = var_of_step[v] with a single space.
  fluxy/operators/regions.py:156
• If flux_{sector}_prior_country is not present in the dataset (skipped at lines 151-152), the subsequent sigma calculation code (lines 157-178) will raise a KeyError when trying to access this variable. Consider checking for the variable's existence before attempting to compute sigma values, or only compute sigma for variables that were successfully processed.

@melodb I had to fix few things to make some of my code work. Please check and let me know
