upgrade @hpcc-js/wasm to 2.20.0 (Graphviz 12.1.0)

Performed by:

npm upgrade @hpcc-js/wasm --save

Also revert the change to wrapper.js added in
761aeec which was an adaptation to a
@hpcc-js/wasm change in version 2.17.0 that no longer is correct. It's
unclear what change caused "@hpcc-js/wasm" to move from using `global`
back to using `window` again.
