new update time wooo

• added sound effects (made in Dn-Famitracker), no more synthesized audio
• added some extra effects
• only the playfield shakes now
• added a combo system, you won't get 10 points for each line anymore, instead you'll get 10 points times the number of lines you clear consecutively
• added a small popup when you get a tetris. this one can also be deactivated in the system menu under the name "sash"
• renamed game from "Tetris for Playdate" to "Playtris". start referring to the game as such.

planned features:

• just looked inside the tetris wiki and the SRS does not seem that hard to implement
• hold
