- Units are now encoded in the acquisition stream if received from a driver. If
the info was not provided by the driver, an empty unit matrix may be sent. It should
be interpreted as default values.
- Header can now be tested if it has measurement units set
- Header copy now copies the units
- Some further support for channel localisation streams, i.e. avoid encoding if no data
- Fixed CMatrix getBufferElementCount() not returning to 0 if some dimension size is set to 0.
