   @brief Creates a `BCDefinition` from an array of integers in an option in the database

   Must be between `PetscOptionsBegin()` and `PetscOptionsEnd()`.

   @param[in]  opt    The option one is seeking
   @param[in]  text   Short string describing option
   @param[in]  man    Manual page for the option
   @param[in]  name   String that sets the name of the `BCDefinition`
   @param[out] bc_def Resulting `BCDefinition`, `NULL` if option is not set
   @param[out] set    `PETSC_TRUE` if found, else `PETSC_FALSE`
