- update to 0.8.2:
  * Makes the pyroomacoustics.utilities.resample backend is made
    configurable to avoid soxr dependency. The resample backend
    is configurable to soxr, samplerate, if these packages are
    available, and otherwise falls back to
    scipy.signal.resample_poly.
  * Fixes typo in materials.json: ceiling_fibre_abosrber ->
    ceiling_fibre_absorber.
  * Adds the missing pyroomacoustics.directivities to the package
    list in setup.py.
  * New global parameters to control the octave bands used for
    simulation. octave_bands_base_freq: the base frequency used
    for the octave bands (default 125), note that together with
    the sampling frequency this will determine the number of sub-
    bands used in simulation. octave_bands_n_fft: lengths of the
    octave band filters (current is default 512 but will be
    changed to 128 in the next release) octave_bands_keep_dc:
    extends the lowest band to include the DC offset, the current
    default is False to match past behavior, but will be changed
    to True in the next release because the filters have less
    oscillations this way.
