• Add GAP.prompt() function which gives a GAP prompt inside Julia
• Add support for Julia keyword arguments on the GAP side

  idiomatic Julia code accessing GAP objects

  which can save time and disk space when rebuilding or reinstalling GAP.jl

  OSCAR do
• Remove the implicit dependency on LinearAlgebra.jl
