Implement genetics for the players

[Oleksii-Kshenskyi]

UPD: OUTDATED info below - this task has been reduced to just the genetics because otherwise the scope is too wide and the SLP would obviously get violated.

This is the key feature of the entire project. Effectively, these are two different features, but they go hand in hand because if we don't have the ability to save a generation, we cannot simulate multiple generations without graphics as we have to somehow save the result of the simulation and then load it into the visualizer.

The features are:

• Genetics for players: players should not be acting randomly, but basing their decisions on their genetics and (potentially?) neural network brains.

Saving/Loading results of the simulation: once the simulation has finished, we have to "breed" players with each other, producing a new "superior" generation of players that (hopefully) is going to know what they're doing a bit better than their parents, and save those genes/brains into a file. Also the visualizer has to be able to then load that saved file and show the results of those "evolved" players playing the game.

^^^ For the above, visit issue #37.

Thinking about this, these are two range-based genes I can implement relatively easily:

• Lethargic/Exploration gene, determines whether a player likes idling around or exploring;
• Cowardice/Courage gene, determines how the player responds to a threat of other player: whether they will run or approach/engage.

To implement these, I need two features that are not yet implemented:

• A "disengage" or "back off jump" action that can move a player two tiles backwards in one turn;
• A basic "line of sight" mechanic that will identify whether the current player is seeing another right now (this is used in the Cowardice/Courage gene to determine whether to fight or flight). NOTE: line of sight should just be a literal straight line for now. Should bother with complex shapes later.

I already have an issue for line of sight mechanics (#10), need an issue for the back off jump action too. For now, this implementation is blocked by those two.

Both #10 and #31 are implemented. Should start planning of this big one. For now, there should be three "scale" genes:

• Lethargic/Exploration gene, determines how much energy a player is willing to spend;
• Cowardice/Courage gene, determines how often a player engages in fights versus runs away (disengages);
• Gorger gene - determines if a player goes for the food if it's in the player's line of sight.

Also, think about one-two other types of genes to implement. Aaaand also think if it's a good idea to start implementing action pipelines (queues) in this one or maybe wait a bit.
