[PD] "espd" play soundfile

[Miller Puckette]

I did something really ugly and stupid... I set the output buffer to 20 
msec so

that Pd could do long-lasting control operations without interrupting audio.

Then I set a metronome to go off at exactly 2048-sample intervals, at 
each of

which I filled an array progressively from a file and started a tabplay~ 
object at

the same instant.  This works only with short files since the SD card 
filesystem

"seeks" by reading through the entire file every time - but you can 
still play long

sounds in principle by splitting them up into many short ones, each one 
an exact

multiple of 2048 samples long.

Here's my patch, enjoy :)
