Subject: [PATCH] Update parse-uboot-dump.py

- Added sanitization for weird chars (mostly null) that randomly came across my serial output.
- Changed len requirements to anything more than 1. My output consistently had hex 3a, which was rendered in the md output as `:`, which would then skip the entire line because len would be more than 2. Output was always smaller than I would expect and caused binwalk to eat dirt.
