Improve benchmark cli, make compatible with deno (#4647)

# Description of Changes

Now we get a `--help` for the benchmark, which is nicer. Also now can
run under deno, with `deno --sloppy-imports -A src/demo.ts` (might be
useful, deno's websocket is implemented in native code while node's is
implemented in JS). I removed the
[BOM](https://en.wikipedia.org/wiki/Byte_order_mark) because it seems
unintentional (only found in `templates/keynote-2`) and was causing a
little bit of weirdness.

Also, fix the rust benchmark client as a follow-up to #4616 

# Expected complexity level and risk

1

# Testing

- [x] Works under deno and has usage
