TTree v5 parsing issue

[tamasgal]

This is a separate issue for something which I believe is unrelated to the issue where it was originally reported (#168 (comment)) by @Cornelius-G

The file has a TTree v5 and we have a runaway file pointer with the latest UnROOT version:

julia> f = ROOTFile("/Users/tamasgal/Downloads/data.root")
ROOTFile with 1 entry and 53 streamers.
/Users/tamasgal/Downloads/data.root


julia> f["proton"]
