Deprecation warnings when using cask because of zipped

[OndrejSpanel]

This line from #137 is causing deprecation warnings when compiling against 0.10.1 with deprecations enabled:

(sigss, argss, ctxs).zipped.map { case (sigs, args, ctx) =>

With fatal warnings this is fatal (sic):

[error] C:\home\runner\work\cask\cask\cask\src-3\cask\router\Macros.scala: method zipped in class Ops is deprecated since 2.13.0: Use xs.lazyZip(ys).lazyZip(zs)

mea culpa on this one. I think if you replace that line with sigss.lazyZip(argss).lazyZip(ctxs), as the message suggests, the warning should go away.

This is in a macro, therefore you do not get the warnings only when compiling the library, but also when you are just using it (linking to it).

I will try to prepare a PR.
