implement WASM (#2054)

While the README had been updated in
[06fce2b](06fce2b),
it was not implemented in the deployment.

When enabled, a log line will indicate if WASM is enabled.

```
[main] INFO  c.n.s.j.p.options.Webassembly - Webassembly (WASM) environment variable detected and will be used.
```
