add_noise function

<dl><dt>mrs_data</dt>
<dd>data to add noise to.</dd>
<dt>sd</dt>
<dd>standard deviation of the noise.</dd>
<dt>fd</dt>
<dd>generate the noise samples in the frequency-domain (TRUE) or
time-domain (FALSE). This is required since the absolute value of the
standard deviation of noise samples changes when data is Fourier transformed.</dd></dl>

Arguments
