Errors building buildmaster

Created by: Zaharid

When building buildmaster as described in the README I get

/home/zk261/nnpdf/buildmaster/filters/INT.cc: In function 'void register_integrability(std::vector<std::unique_ptr<Buildmaster::CommonData> >&)':
/home/zk261/nnpdf/buildmaster/filters/INT.cc:22:15: error: too many initializers for 'const std::array<std::__cxx11::basic_string<char>, 2>'
   22 |     "INTEGXV8"};
      |               ^

Others have gotten other errors in that file such as

/buildmaster/filters/INT.cc:20:5: error: excess elements in struct initializer
    "INTEGXV",
    ^~~~~~~~~
