NAM Oversampler v1.3.0

[DLC86]

• Added separate filter choice for offline rendering.
• Added additional filter types: Min Phase FIR and Polyphase FIR.
  The former is slightly heavier on the cpu than IIR but creates less phase rotations in the audible portion of the spectrum, the latter is a more efficient version of the linear phase FIR.
• Improved filter calculation logic: now it takes into account also the NAM model's sample rate.
  Example: if the project sample rate is 96 kHz but the model sample rate is 48 kHz, the filter doesn't let pass anything above 24 kHz as there's no realistic info contained in the model for frequencies above 24 kHz.
  If instead the model sample rate is 96 kHz too, the filter will let signal extend up to 48 kHz, as in this case the model was trained on those frequencies as well and they should be represented when the project sample rate allows it.
  NOTE: this change doesn't affect aliasing reduction
• Added current oversampling indicator on the main page, next to the logo.
• Fixed stereo mode not being engaged in some DAWs/hosts.
• Fixed a bug that might cause a wrong convolution time-scaling, thus a shifting of the model's frequency response, when the project sample rate is a non-integer multiple of the model sample rate (e.g. 48 kHz model in a 44.1 kHz project)
• Missing output on Mac/AU on 96 kHz projects should be fixed (cannot test this personally)
• Plugin not loading in Reaper on Mac should now be fixed (cannot test this personally)
• DAW/host presets now correctly recall all oversampling and filter parameters
• Added VST3 version for Linux (experimental - no GUI)
