[Suggestion] Allow output to stdout

[apcamargo]

Currently, the only way to get a bam file from puffalign is to write a sam and then convert it in a separate command. If puffalign could output to stdout it would be possible to pipe it into samtools to get a bam directly.

This is a great suggestion. We'll work on it.

Thanks Rob!

I just started testing puffalign and I'm really excited with it. I may open some other issue tickets soon :)
