Libxc components are reject in the method block

[kjh-giesbertz]

Describe the bug
In the method block, the correlation and exchange components are defined as Literals, but does only include orca versions whereas orca is also perfectly happy to have Libxc versions specified

Example
BlockMethod(correlation="gga_c_p86") is rejected but perfectly acceptable for orca itself

Version:

• OPI [2.0]
• ORCA [6.1.1]

Additional context
The revdsd-pbep86 functionals are defined with the original P86 which uses the PZ81 as LDA correlation (QChem and Libxc definition). Orca uses the VWN5 instead, so I would like to be able to define a patched double hybrid. The ldaopt does not have pz81 available, so Libxc is needed here.

Thank you for raising this issue. We will see that we also include the LibXC versions in the Literal.
