chore(io): delete MED/Code_Aster element glue tables

Remove the standalone connectivity permutation maps and element-name tables
that wired Code_Aster MED exports into legacy JuliaFEM symbols.

- Drop `src/io/aster_reader.jl` from the default tree (no longer pulled into
  `JuliaFEM`).

-Nodes are different order in Code Aster compared to ABAQUS. This is yet
-incomplete mapping between the permutations. Most of this is still a
-great mystery.
