I see a slight overhead when extraction is perfomed. It also seems that Java 11
has got slower.
But with 16:

> Exclude lib/jansi-native/osx
> (+) Maven runs without popup/warning
> (?) no additional extraction of native libraries
> (-) inconsistent use of JAnsi for OSes
> Don't unpack to lib/jansi-native
> (+) consistent use of JAnsi for all OSes
> (-) Maven will have extra overhead for every run due to extracting
> jansi-native
> Unpack lib/jansi-native on first use
> (+) consistent use of JAnsi for all OSes
> (-) In general we consider conf/ as the only directory that can be changed
> after installing. Now lib/jansi-native would become a "dynamic" directory.
> Get a signed native library for MacOS
> (+) consistent use of JAnsi for all OSes
> (-) somebody needs to build & sign the JAnsi native lib (requires a Mac and
> an Apple Developer ID)
