Changed

• Faster import (#349): import musicalgestures dropped from ~0.65s to ~0.52s by deferring import numba (it pulls in LLVM). The @jit kernels in directograms/impacts/warp now compile lazily on first use. The nested directogram case (directogram calls matrix3D_norm) is handled by compiling the inner kernel and rebinding the module global before the outer one compiles. Continues the startup-speed work from 1.6.3.
• Added the missing parameter type hints to mg_warp_audiovisual_beats (follow-on to #345).
