Direct import of newer acq data

[dominikbach]

Feature Description

Rather than importing matlab-converted acq files, read them directly into matlab.

Could be implemented either via the python tool Bioread: https://github.com/uwmadison-chm/bioread
(but probably this issue would need to be fixed: uwmadison-chm/bioread#39)
Or directly in matlab, using their documentation of the internal acq file structure.
