spectrogram~ v2.0 package now available via Package Manager

Hi all,

v2.0 of the spectrogram~ object suite is now available via the Max 8/9 Package Manager.

Key updates:

1. New in-place buffer~ editing functionality:

   • ability to edit inside or outside selections (including drawn closed shapes via a new "draw" mouse mode (@mouse_mode 2))

   • targeted spectral gain, deletion, isolation

   • targeted frequency and pitch shifting (with multiple mix/replace/copy modalities)

   • up to 20 undo/redo states

   • all functionality exposed via messages and also via right-click menu in the spectrogram~ UI.

2. Frequency Reassignment functionality!

   • check out the new @freq_reassign attribute (demonstrated in the Display tab of the help patcher).

3. Color scheme updates:

   • Added 5 new perceptually uniform, colorblind-friendly color schemes

   • Added Turbo color scheme (high-contrast rainbow colormap, Google's improvement on Jet)

   • This replaces earlier Classic color scheme.

   • Added Hot color scheme (black->red->yellow->white)

4. New JSUI Toolbar & Mode Objects:

   • spectrogram.toolbar.js: 15-button JSUI toolbar providing convenient method to send zoom/view/select messages.

   • spectrogram.modes.js: 3-button radio-style JSUI for mouse mode selection (Select, Move, Draw).

5. Large SIMD-accelerated FFT performance improvement (SSE on x86, NEON on ARM) - replaced kiss_fft with pffft.

All help patches, snippets, reference docs have been updated accordingly.
