fluidsynth: update to 2.4.0.

New Features

    Implement MSGS-style Drum Note Cut (#1199)
    Support KAI audio driver on OS/2 (#1332, thanks to @komh)
    Add support for AWE32 NRPNs (#1346)
    Add support for Polyphone's sample loop mode release (#1398, thanks to \

Breaking Changes

    LASH support has been removed (#1285)

Musically Breaking changes

    The default settings for reverb and chorus have been tuned to provide a more \ 
natural perception (#1282, thanks to @es20490446e)
    The behavior of the volume envelope's delay phase was previously incorrect \ 
(#1312)
    The ModLfoToVolume generator was not able to increase the volume (#1374)
    Fluidsynth's default device-id was changed, allowing it to process (most) \ 
SysEX events without further configuration (#1382)
    Previously, some modulators were treated in a non-standard way (#1392, \ 
#1389, #1068)

Bug Fixes

    Bogus interpolation of IIR filter coefficients could have caused audible \ 
clicks and cracks (#1345) - yet there is still a potential for clicks and \ 
cracks, see #1415
