CamillaDSP for Room Correction

[Snoopy8]

At long last, CamillaDSP may make it in the next release, 1.4.4.🤞

As some people know, setting up DSP is not easy even with using a GUI like CamillaGui which is decent.  Suggest adding some templates (pre-configured setup) to help users start with:

• High and low pass filter
  
• Delay 
  
• Phase invert
  
• PEQs
  
• Convolution
  
• etc...
  

Just have to be careful with supporting CamillaDSP because we should only support the tool but users will have questions on DSP filter design.  Where do we draw the line, especially when users are new to DSP?

Have already written a Wiki page on room correction software and will improve it when CamillaDSP is out..
