v0.12.0

Breaking changes

• requires-python is now >=3.12 (#864). Users on older interpreters stop resolving new releases.
• sympy is no longer a runtime dependency (#947).
• quantecon.util.common_messages is removed (#864). It held one string for a Numba-fallback path that no longer exists, and nothing imported it.
• tic, tac, toc and loop_timer now emit DeprecationWarning (#833). Use the Timer context manager and timeit instead; removal is scheduled for v1.0 (#786).
