Adding agent types to hashkat-lib

[arminms]

• std::uint16_t will be the last template argument (W)
• it must be a vector of std::uint16_t types
• VauleType will be renamed to V
• agent type names will be stored as std::vector<std::string> at_name_
• agent type name can be found using std::string type_name(std::size_t type_idx) const
• agent type can be found using W agent_type(T n) const
• initialization of agent types from config can happen in constructors
• agent types add weights are stored in std::vector<V> at_add_weight_
• changing bool network::grow() to bool network::grow(W at)
• changing signal<void(T)> grown_signal_type to signal<void(T,W)> grown_signal_type
• during grow, type of the agent will be decided using the algorithm in original hashkat
• adding std::vector<std::vector<T>> at_agent_ids to network class to hold agent_list for each agent type
• adding std::vector<std::vector<T>> at_agent_per_month to twitter_follow class to hold agent_cap for each agent type
• calculation of follow action weight must be based on the agent type monthly follow weights in twitter_follow::do_update_weight(const TimeType&) (requires Adding a constant pointer of engine's time as member variable to actions #14)
• creation of follow ranks (bins) for each agent type
• updating follow ranks (bins) for each agent type in twitter_follow::agent_added(T,W) and twitter_follow::update_ranks(T,T) member functions
