https://github.com/korginc/logue-sdk/blob/ab654af0e29e5eb6eab7289d05699b45417d1f68/platform/prologue/inc/utils/float_math.h#L680

Current fastpow2f suffer from the lost of precision. depending on the input value it could be times worse then with faster2f

offset must be applied like in the original verion https://github.com/pmineiro/fastapprox/blob/master/fastapprox/src/fastexp.h#L54

@etienne-korg Please refer to this commit in my fork as current fastpow2f is imprecise https://github.com/dukesrg/logue-sdk/commit/8874c04e0f030d51378cff00a4061797d8a5b461
