perf: defer matplotlib imports and lazy-load plot submodule#330
Conversation
Replace module-level matplotlib imports with autoarray.plot.utils wrappers across all plot files. Move plot_utils.py to autogalaxy/util/ to break a circular import between plot submodules and plot/__init__. Lazy-load the plot submodule via __getattr__ in autogalaxy/__init__, deferring ~0.3s of matplotlib import cost to first plot access.
