Request body from stdin

[gbmor]

I thought this would be a handy addition. It will also make requests with a body more easily scriptable.

• Checks if data is being passed via stdin, and if so, uses it as the request body (and ignores -b / --body). This does not try to guess the content-type, it only replaces the -b flag.
• If data is not being passed via stdin, use whatever is being passed via -b (or nothing if the flag is omitted).

Example with redirection:

$ cat myrequest.json
{
  "foo": "bar"
}

$ hopp-cli post -c js http://example.com <myrequest.json

Example with pipes:

$ echo '{"foo":"bar"}' | hopp-cli post -c js http://example.com

If you combine stdin and -b, then -b is ignored:

$ echo '{"foo":"bar"}' | hopp-cli post -c js -b '{"other":"data"}' http://example.com

Request body: {"foo":"bar"}

But you can still use -b by itself:

$ hopp-cli post -c js -b '{"other":"data"}' http://example.com

Request body: {"other":"data"}

Also, would be great if you could add about the same to the Readme

@athul no problem, I've just added a README change to the PR.
