// Unsigned integers
var a = LEB128.encode(462644);
// Uint8Array (3) [ 180, 158, 28 ]
var b = LEB128.decode(a);
// 462644
var c = LEB128.decode([0xA6, 0x87, 0x90, 0x04])
// 8651686

// Signed (negative) integers
var d = LEB128.encode(-128383);
// Uint8Array(3) [ 129, 149, 120 ]
var e = LEB128.decode(d, 0, true); /* offset = 0, negative number */

var f = LEB128.decode([0x01, 0x81, 0x95, 0x78], 1, true)
