Support more instrument/effect categories

heres a chatgpt list of effects (not exhaustive)

Compressor:
    Reduces the dynamic range by attenuating peaks, providing a more even sound. Commonly used in mixing and mastering to control loudness.

Limiter:
    A more aggressive form of compression designed to prevent audio signals from exceeding a set threshold. Often used in mastering to prevent clipping.

Expander:
    Opposite of a compressor, it increases the dynamic range by reducing the volume of sounds below a certain threshold. Used to create more contrast in dynamics.

Gate (Noise Gate):
    Similar to an expander but more focused on reducing or eliminating unwanted background noise by cutting audio below a certain level.

Equalizer (EQ):
    Allows you to adjust specific frequency bands in the audio spectrum. Can be used for tonal shaping, corrective EQ, or creative effects.

Saturator:
    Introduces harmonic distortion to add warmth, character, or "grit" to the sound. Saturators are often used to emulate analog tape or tube saturation.

Distortion:
    Alters the audio signal to create a more intense, gritty, or "crunchy" sound. Distortion is used in various music genres, especially rock and electronic music.

Reverb:
    Simulates different acoustic environments to add depth and ambiance. Can range from subtle room reverb to expansive hall reverb.

Delay:
    Repeats the audio signal with a time delay, creating echo effects. Delay can be used creatively for rhythmic patterns or subtle ambiance.

Chorus:

Creates a richer, fuller sound by combining slightly delayed and detuned copies of the audio signal with the original.

Flanger:

Creates a sweeping or "jet plane" effect by mixing a delayed signal with the original, with the delay time modulated over time.

Phaser:

Similar to flanging, it creates a sweeping effect by shifting phase relationships within the audio signal.

Exciter:

Adds harmonic content to brighten the sound. Often used in mastering to give tracks more presence.

Pitch Shifter:

Alters the pitch of an audio signal. Can be used for creative effects or to correct pitch.

Vocoders and Harmonizers:

Vocoders create robotic-sounding vocals, while harmonizers generate harmony layers from a single vocal track.

I already have these categories:

• Compressor
• Equalizer (EQ)
• Distortion
• Reverb
• Delay
• Chorus
• Phaser
• Pan
• Filter

These I don't have currently:

• Limiter
• Expander
• Gate (Noise Gate)
• Saturator
• Flanger:
• Exciter
• Pitch Shifter
• Vocoder/Harmonizer

I think it would be a good idea to support them.
I will need to consider whether some can be combined into the same category to reduce the number of additional navigation items.

heres a saturator one jatinchowdhury18/AnalogTapeModel#317

the problem is the surge team said i did it wrong, you can look at the discord for what they said
