Update Acoustics Module

[jmcvey3]

Enhancements:

• Adds ability to convert sound spectral densities to millidecade format (https://doi.org/10.1121/10.0003324)

Bugfixes

• Refactors band-averaging for spectral density levels and sound pressure levels. This refactor avoids losing information at frequencies located at band boundaries, and conducts all of the band-averaging immediately after the PSD calculation.

The jupyter notebook has been updated with these changes as well.
