Parse error in upstream.Parse

[iamseth]

When I build and run locally, I'm getting a parsing error for upstream. It looks like in my case, I'm getting a leading space "parse frequency: strconv.ParseFloat: parsing \" 0.0\": invalid syntax" row="[1 Locked OFDMA 1 0 0.0 0.0 ]".

I was able to fix this locally by injecting a call to strings.TrimSpace between the calls to strconv.ParseInt and strconv.ParseFloat

I can create a PR if you'd like. The README mentions to discuss first so here I am :).

Here's how to repro.
