HexBox column labels & hex for struct arrays

[Ste1io]

Excellent work on this tool. Made a couple modifications for my own use, feel free to merge if you like.

hi, thanks for the input but I found a simpler way to add hex support, I also updated simply the hexbox project, which now includes a switch to show the column headers, no need to add an extra label

have a nice day
