zignal 0.4.0

Highlights

This release introduces image scaling for terminal graphics (Sixel, Kitty)
and allows direct image instantiation in Python.

It also includes significant refactoring of terminal state management and
the Sixel processing pipeline, alongside performance optimizations for
Sixel color quantization and dithering. Python bindings received enhanced
docstrings and type hints.

BREAKING CHANGE: Canvas.drawText method parameter order changed from
(x, y, text, font, color) to (x, y, text, color, font).
