Adds `scipy` and `matplotlib` dependencies.
Changes `--interpolate=<inverval>` to use splines to interpolate, as do all other operations that interpolate.
Adds `--interpolate-linear=<interval>`, which does linear interpolation operation as `--interpolate` now uses splines.
Adds finalize script: `python3 -m synth_mapping_helper.finalize <input_map.synth> <output_map.synth>`, which moves walls up to compensate for game showing them differently than the editor. Supports `--plot` to plot velocity and acceleration and `--revert` to undo finalizing.
