Blue Willow b6c0d07dc8 Document AudioEffectSpectrumAnalyzerInstance, clarify relationship with AudioEffectSpectrumAnalyzer
Fully document AudioEffectSpectrumAnalyzerInstance, including the weird
return value of its sole method, and add a link to it in
AudioEffectSpectrumAnalyzer to make it easier to figure out how to use.

<brief_description>
Queryable instance of an [AudioEffectSpectrumAnalyzer].
</brief_description>
<description>
The runtime part of an [AudioEffectSpectrumAnalyzer], which can be used to query the magnitude of a frequency range on its host bus.
An instance of this class can be acquired with [method AudioServer.get_bus_effect_instance].

<description>
Returns the magnitude of the frequencies from [param from_hz] to [param to_hz] in linear energy as a Vector2. The [code]x[/code] component of the return value represents the left stereo channel, and [code]y[/code] represents the right channel.
[param mode] determines how the frequency range will be processed. See [enum MagnitudeMode].
