Add ACE parsing and plotting capabilities

[dodu94]

Description

the endf dipendency is added to f4enix in order to be able to parse ACE files and obtain continous XS for nuclides. On top of this, a method is added to get a XS not only for nuclides but also for elements and materials. Moreover, the cross sections can also be collapsed into pre-defined energy groups.

Additional dependencies introduced.

• endf
