* ⚡ Send objects-map pages to the worker without a second encode
When switching between pages on a large file e.g Material Design Icons, there's
some UI freeze from :index/initialize encoding object map shapes to send to the
worker. An objects map already stores the encoded JSON for each shape, and
`encode-str` was wrapping those strings in a second layer of JSON on the main
thread.
We can just transmit the already encoded JSON in a js/Map alongisde the
payload, similar to :blob, so structured clone just copies the strings verbaitm
without re-encoding. To do this this PR adds two functions to ObjectsMap that
converts to and from a js/Map.
The "Main components" page of the Material Design Icons has ~30k objects, so
this reduces the freeze when switching pages from 306ms -> 189ms (1.63x) on a
release build.
