A couple fixes and a bunch of download files

Fixed a rare bug letting you jump diagonally a lot higher while easing towards ladders.

Taking advantage of Pico-8's recently introduced custom waveform feature for SFX, slightly improved kong's "roar". Small fixes to a couple other sfx, avoided clicks.

Now the game is released in a bunch of file formats, Cartridge (p8.png) and binaries for various OSs.
Running as executable the flicker effects should work way better and consistently.
