Export serdes from libcheloniajs

[taoeffect]

Problem

Right now in libcheloniajs we are importing serdes but we aren't exporting it.

So in GI currently we are separately importing serdes.

If there's a version mismatch between these two it would mean multiple versions of serdes could get bundled.

Solution

Export serdes from libcheloniajs and import it in GI directly from the chelonia lib.
