Add DAPHNEEth and DAPHNEEthStream support to generate_fakedata

Add optional fragment_type parameter to generate_fakedata and handle
det_id=2 (HD_PDS) for DAPHNEEthStream (frame_size=2008,
time_tick_diff=280) and DAPHNEEth (frame_size=1864,
time_tick_diff=1024). Previously only det_id=3 (WIBEth) was supported.
