SDMorse.h

// Read a text file and send the characters through a MorseEncoderSine
//
// Requirements before calling:
// - SD set up and valid filename passed in
// - AudioSynthWaveform configured with connections to output and pointer passed in
// 
// TODO:
// - If first character is *, read the line for WPM (and frequency?)
