Calculate medium ahps in chosen trials after spikes in the spk_win. mAHPs are
defined as hyperpolarization peak value between two spikes relative to the spiking
threshold of the prior spike, excluding the fast AHPs range right after the
prior spike. Choose spikes to avoid Ih current and sAHP.
Parameters:
lat_win (array_like) - 2 scalars, mininum latency for mAHP, window for fAHP,
and minimum interspike interval to include ahp.
spk_win (array_like) - 2 scalars, begin and end of the window of spikes
param_file (String) - directory to parameter files for spike detection
output_file (String) - dirctory to output file of medium ahp data of all
