work around boot instability issue with a delay setting up codec in TTS

Browse source 
The `codec` seems to hang sometimes during `Setup8kStereo` at boot.
Did not get to the bottom of it, but suspect that the RTC I2C init
sequence is interfering with the codec init sequence. This might
be resolved while also fixing #467, but for now, a short delay
on boot works around the problem.
