community/gnuplot: upgrade to 6.0.0 & adopt aport
https://sourceforge.net/p/gnuplot/gnuplot-main/ci/branch-6-0-stable/tree/RELEASE_NOTES
Test watchpoints.dem
fails with line 81: undefined function: FresnelC
, so i have added a new aport libcerf
which enables that function, and added it to makedepends
of gnuplot
.
