CLJS builds don't work

[RokLenarcic]

When compiling CLJS with konserve version 0.6.0-alpha3, you'll get this error:

[:main] Compiling ...
[:main] Build failure:
The required namespace "incognito.fressian" is not available, it was required by "konserve/serializers.cljc".
"incognito/fressian.clj" was found on the classpath. Maybe this library only supports CLJ?

Seems like project is using fressian and it's not available in CLJS
