Feature request: REPL

[grimnight]

Instead of using cat page.html | hq '{something: .something}' repeatedly until it works,
it might be better to use something like cat page.html | hq --repl to get a prompt:

> {something: .something}
{
  "something": "something"
}

for quick development, this could also help with #33 .
There could also be SQLite style .help or Postgres style \? commands.

Would this make sense for hq?

I love this idea, I’ll have a go at adding it

Rather than bundle a REPL directly into the tool I decided to try and create a WASM playground for hq. It's published here: https://orf.github.io/hq/

I'll be expanding and making it better later on, but let me know what you think

Cool but repl useful for people who only have a term to work in for some backend work.
