tree | icepick fails

[Byron]

Maybe it's not even supposed to work, yet I thought I should let you know anyway.

This is due to the way we iterate through the strings. I have a branch the iterates using chars(), but there is a performance penalty.
I'll push the branch so you can see if it solves the issue.

When compiling the unicode_regression branch, the example above works for me.

Considering that we are in Rust, the performance penalty might be preferred over the crash above. It's probably still fast enough for common usage scenarios.

After all, first it should work right, before one can spend additional time to make it work fast.

It's a nice tool by the way, previously I used tree | less, which is somewhat inferior.
