feat(insim): add ObjectFlags enum with FLOATING value (0x80)

[mkapal]

Usage example:

import { InSim } from 'node-insim';
import { ObjectFlags, PacketType } from 'node-insim/packets';

const inSim = new InSim();

inSim.on(PacketType.ISP_AXM, (packet) => {
  packet.Info.forEach((info) => {
    if ((info.Flags & ObjectFlags.FLOATING) !== 0) {
      // This object is floating
    }
  });
});

Closes #80
