add a more complex example of fetching subnotes to readme.
support multiline stdin on decode, encode and fetch, and improve the helpers.

-# nostr army knife
+# nak, the nostr army knife

-this repository contains two things:
+install with `go install github.com/fiatjaf/nak@latest` or
+[download a binary](https://github.com/fiatjaf/nak/releases).

-## a command-line tool for decoding and encoding nostr entities and talking to relays
+## what can you do with it?

-Install with `go install github.com/fiatjaf/nak`.
+take a look at the help text that comes in it to learn all possibilities, but here are some:

-It pairs nicely with https://github.com/blakejakopovic/nostcat using unix pipes.

 	Description: `outputs a NIP-01 Nostr filter. when a relay is not given, will print the filter, otherwise will connect to the given relay and send the filter.

-example usage (with 'nostcat'):
-		nak req -k 1 -a 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d | nostcat wss://nos.lol
-standalone:
-		nak req -k 1 wss://nos.lol`,
+example:
+		nak req -k 1 -l 15 wss://nostr.wine wss://nostr-pub.wellorder.net
+		nak req -k 0 -a 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d wss://nos.lol | jq '.content | fromjson | .name'
+
+it can also take a filter from stdin, optionally modify it with flags and send it to specific relays (or just print it).
+
+example:
+		echo '{"kinds": [1], "#t": ["test"]}' | nak req -l 5 -k 4549 --tag t=spam wss://nostr-pub.wellorder.net
