Pyrato

------------------
* Use pyfar audio objects to store RIRs and EDCs (PR 7)
* Drop support for Python 3.7 (PR 14)
* rename RT estimation function to `reverberation_time_linear_regression` (PR 13)
* use pyfar's impulse response start finding function and fractional octave filters, respective functions are deprecated and will be removed in pyrato 0.5.0 17 (PR 7)
* Add ISO 3382 compliant dynamic range threshold to `energy_decay_curve_truncation`, add similar functionality to `energy_decay_curve_chu` (PR 18)
* Bugfix for wrong truncation time for multichannel RIRs (PR 19)
* Update of the documentation style and adaption of the shared gallery homepage (PR 22)

------------------
* Hotfix for deprecated generation of nested ragged sequences in Lundeby's intersection time algorithm.
