      core: save stackmax by tmin_ms
      
      The high frequency ASPO data set (used by Jose) requires short time windows, shorter than 1 second. stackmax traces have therefore repeatedly been overwritten. tmin_ms as file name solves this issue in this case. Using tmin_ns made the trace names lengthy and I don't think anyone needs this (until now at least). Hence, it's a compromise.

      Merge branch 'fft_convolve' into 'master' · 59c4ebe6

      ifc: use scipy fftconvolve instead of numpy convolve.
      
      Performance increases significantly for long time windows when using fftconvolve over convolve. I tested two data sets: ASPO and the alentejo example dataset. Checkout the attached terminal output of the alentejo example. 
      At the top: the current master branch version. The numbers in between the lines are processing times needed for that specific time window.
      At the bottom: the proposed version using fftconvolve. It's a bit faster as you can see.
      However, the ifc pre-processing of the ASPO  application of Jose accelerates by a factor of about 35 when using fftconvolve!
      The maximum relative (!) differences in trace amplitude when comparing both versions if about 1e-6 . Hence, negligible, I think. Also, detections are identical.
      ...Just faster.
