Warning when building with v1.9.660 of the ClojureScript compiler

[khellang]

The ClojureScript team recently released v1.9.660 with a new warning for variadic signatures in protocol methods:

NOTE: that this release introduces a new warning for incorrect code which employs variadic signatures in protocol method implementations. Such code will continue to work with this release. Be sure to update any code or libraries that make use of this construct so that protocol implementations match some existing signature.

This results in a compiler warning when building our application using Reagent:

WARNING: Protocol IFn implements method -invoke with variadic signature (&) at line 61 ..\target\cljsbuild-compiler-1\reagent\impl\util.cljs

Oh, sorry. Didn't see #303. Thanks for fixing it so quickly 😉
