.parse(fs.readFileSync('demo.dem'));
const IN_JUMP = 1 << 1;
const registeredJumps = demo
.findMessages(DemoMessages.UserCmd)

Credits
inolen/bit-buffer for BitStream and BitView. I ported it to TypeScript because Deno cannot bundle npm specifiers
and any other bundler is not good enough. Also this port significantly improves typings which means less errors etc.
