change sprint movement to lunge with i-frames (short duration invincibility)

[plexsoup]

The current sprint movement isn't very satisfying.

Make the default base speed a bit faster and Swap out sprinting for a lunge/dash move. During the lunge, player should be invincible, so it's good for dodging and getting close.

Avarice - Cat That Draws Things: In that same vein, I would suggest a decrease in how quickly stamina regenerates; regen that's too fast trivializes the combat by allowing the player to spam the dodge button without consequence

dash is in the game.
