At tick number 118792 there is a PlayerHurt event with EqUnknown weapon. In the game the player was hurt with molotov projectile, which is stored as "molotov_projectile" in the raw event data. However, in the library we don't have mapping for this string (although we have it for "molotovprojectile"). I assumed that the similar problem may arise with other types of projectiles so I added appropriate mapping for them as well.
