Progress bar crashes on terminal resize

[squarism]

Running the progress bar from the example docs. Resize the terminal while the progress is going.
Tried iTerm and OSX terminal, same result.

I was poking around to find more behavior but ran out of time.

I've been using the progress bar a lot but haven't been resizing the screen. Thanks for reporting. Would you find time to investigate further?

I think I have made progress on this with #12 . Of course it's up to you if you like the change. 🌻

I've released v0.8.1 with a patch. I've decided to only trap interrupt signal, trapping exit would swallow genuine exceptions. The resize has been simplified and tested to properly work inside threads and actually resize the progress bar on terminal size change. Please let me know if this works for you.

Nice! Seems to work and the change makes sense. Thanks for merging a bit of it. Glad to help. 🌻
