feat(usePantry): Add support for multiple dists in distributable.

The same as #196

I added a fixture and it appears to fail, I guess we need to wrap the new fetch code.

I added a fixture and it appears to fail, I guess we need to wrap the new fetch code.

It checks and tries to find the first working URL. For invalid URLs, it's supposed to fail.

Maybe cscope one would be a good example:

distributable:
    - url: https://downloads.sourceforge.net/project/cscope/cscope/v{{version.raw}}/cscope-{{version.raw}}.tar.gz
      strip-components: 1
    - url: https://downloads.sourceforge.net/project/cscope/cscope/v{{version.raw}}/cscope-{{version.raw}}.tar.bz2
      strip-components: 1

Okay, I misunderstood the fixture. I've added a catch block to handle exceptions as well

And thus it passes that test. Sorry for the delay

Tremendous, thanks for the work.
