Bumps xlsxwriter from 3.2.9 to 3.3.0.

Changelog

Sourced from xlsxwriter's changelog.

Release 3.3.0 - October 22 2026

• Added the :func:set_zoom_to_fit() method for chartsheets. It ensures that a chartsheet is zoomed automatically by Excel to fit the screen even when the window is resized.

• Added alt text description and title options to worksheet Tables.

• Added the :func:use_custom_theme() method to change the default workbook theme to a user supplied .thmx, .xlsx or theme1.xml file, along with the default_format_properties, default_row_height and default_column_width constructor options to change the default font and cell size to match the theme.

  :feature:1163.

• Changed the exception raised for an unsupported source type in Image() and an unsupported theme type in use_custom_theme() from ValueError to TypeError.

• Fixed issue where conditional format rule priorities were out of order when a cell range was repeated after a different range. The priorities now follow the order in which the rules were added.

• Fixed issue where autofilter() didn't check that the range was within the worksheet limits, which could produce a corrupt file for large worksheets.

  :issue:1179.

• Fixed spurious "Invalid cell reference" warning when a chart series used a defined name with a sheet reference.

  :issue:1173.

• Fixed the width and height detection for large GIF images and for top-down BMP images, and added extra image dimension validation.

  :pull:1188 and :pull:1189.

• Migrated the packaging configuration from setup.py to pyproject.toml with the license declared as a PEP 639 SPDX expression.

  :issue:1201.
