Downgrade coremem: 0.4.8 -> 0.4.5

The binary build for 0.4.8 was lost during the maven.scijava.org
downtime last month. Looking at the source code at
https://github.com/ClearVolume/coremem, I do not know where this
version came from, as the version string there is only 0.4.5.
The URL https://github.com/ClearControl/CoreMem is defunct.
