Delete binreader cask

[lukateras]

Their site doesn't seem to be functioning:

• http://www.binreader.com/
• http://www.binreader.com/Binreader_v1_0_beta1.dmg

Nor I found any other reliable place to download it.

I agree about these deletions, and am grateful to @yegortimoschenko for the tremendous contributions.

But sometimes a site goes down only temporarily. For example, manytricks.com was down just today, so their associated Casks didn't make it into #6686. But now I see that manytricks.com is back up.

So, I propose to create a homebrew-boneyard repo within the caskroom org, by analogy with Homebrew's boneyard:

• seemingly dead Casks could be placed in the boneyard for other contributors to find
• "documented dead" Casks like bodega.rb would just be deleted, no need to use the boneyard
• knowing the backstop is present would encourage us to delete more freely
• at our current size, deleting must become a necessary habit of maintenance. Feeling free to delete would be a good thing.

@rolandwalker That would be great.
