Replay parsing failures

Trying to load replays at load_level=2 and sc2reader errors out with the following stack trace:

struct.error: unpack requires a buffer of 4 bytes

Script runs successfully when load_level=0

Here's the relevant output of sc2parse (only the errors):
pastebin

Here are archives of the offending replays:
sc2reader_replays_1.zip
sc2reader_replays_2.zip
sc2reader_replays_3.zip
sc2reader_replays_4.zip
sc2reader_replays_5.zip

Reproduce the failure with the supplied replay archives at load_level=2, then inspect sc2reader/readers.py around line 274 and sc2reader/decoders.py around read_uint32. Compare the behavior with the sc2parse errors and confirm that all supplied offending replays can be loaded without the buffer-underflow error.
