New Source File Layout

[Makuna]

Is your feature request related to a problem? Please describe. Current software source files have grown not only in count, but also in volume of source within each file. Often files contain high multiples of classes that while related they make it hard to find specific classes and manage them.

Describe the solution you'd like

• Create a hierarchy of folders that organize the files.
• Break single files out into "one class" to "one file".
• Rename files to reduce duplication in file name and folder names within the hierarchy (no need for ESP32 in name if under ESP32 folder).

Current Arduino requires at least a single public include file at what is considered the root of source (not examples).

NeoPixelBus/src/

beyond this is left to the library writer and is assumed as the starting root.

methods/<platform>/<method files>
    methods/esp32/NeoEsp32I2sMethod.h  
features/<element & feature files>  
    features/NeoGrbFeature.h  
topologies/<layout & topology files>  
    topologies/NeoMosaic.h  
colors/<color and gamma files>  
    colors/RgbwColor.h
buffers/<buffer files>  
    buffers/NeoDib.h  
animations/<animation files>  
    animations/NeoEase.h

And for examples, which start at the root of library under examples folder

NeoPixelBus/examples/

and again beyond this is left to the library and will be assumed in this list

<platform>/<platform specific examples folders>/  
    Esp32/NeoPixel_Esp32_I2sParallel/  
topologies/<topology examples folder/  
    topologies/MosaicTest/
animations/<animations examples folder>/  
    animations/NeoPixelCylon/  
images/<image and buffer examples folder>/    
    images/NeoPixelDib/  
advanced/<advanced feature examples folder>/  
    advanced/NeoSegmentBus/
<introduction examples folder>/
    HelloNeoPixel/
    HelloDotStar/

NeoMethods renamed without Neo at front? Matches DotStar names better. Neo400Kbps is the exception.

https://github.com/Makuna/NeoPixelBus/pull/683 Just methods directory and move files into it. Still no platform directories yet.
