Default Incorrect 8 bit PCM render (FIXED)

When I render a WAV file with few seconds of silence in 8 bit PCM (without dither), and then add the resulting WAV file to a project, the meters indicate there is a DC signal of -48.2 dB instead of -inf dB (the render meter did indicate -inf dB BTW).

Apparently REAPER (v5.x, don't know about v4.x) seems to think that the 8 bit PCM value for silence is 127. However, I think this is incorrect, 128 is the correct value, and Audacity seems to agree with me.

I don't need 8 bit PCM myself, but I thought somebody else might. If so, and if this indeed is a bug, then I guess it would be nice if this could be fixed.

[For devs and/or those interested: I happened to spot this while adding 8 bit PCM support to WDL's WaveWriter and pcmfmtcvt (see the 'wavwrite' branch of my WDL repo).]
