My own version of AudioSynthWaveform. Sine is generated with arm_sin_q15() (but is slower) and the other three waveforms are generated without using tables.

Syncing changes to level & volume setting routines
I forgot to sync the changes relating to things like 'dac_vol_right(..)'
& 'dac_vol_left(..)' removed in favor of 'dac_vol(left,right)' instead;
applies to 'volume(..)', 'lo_lvl(..)' & 'dac_vol(..)'.

Various corrections and addition of calcBiquad(..);
removed 'route(..)' due not easily supportable atm. Updated
'dap_enable(..)' in lieu of route. Fixed dap_audio_eq_band(..) bad use
of unsigned. Changed 'updateCoefs(..)' so default behavior is not reset
other three elements of state.

Revert line out level value
Something wrong with my attempt to apply the math in the datasheet,
CHIP_LINE_OUT_VALUE is better set to 0x0505 rather than 0x0D0D.

Add delay to coefficient loader fix.
I thought the time taken to read back and then write zero back to the
DAP_FILTER_COEF_ACCESS WR bit would be enough but coefficients did not
load to the selected filter, tried 1ms delay instead still didn't work -
chances are that either not zero-ing or only zero-ing just before
writing the DAP_COEF_WR_xx_xSB registers would be fine but for now I'd
prefer to zero it sooner than later.
