v0.4.0

Summary

This release adds new getter methods for fit errors, extrapolation curves, etc. in ZNE factory objects as well as custom types for noisy operations, noisy bases, and decompositions in PEC. It also includes small updates and fixes to the documentation, seeding options for PEC sampling functions, and bug fixes for a few non-deterministic test failures.
