Feature complete implementation of NWC in PHP finished!

Thanks to generous contributions the project got activated and then got accepted into the NWC Hackathon Grant process, so I got to work fast!

As PHP still doesn't have proper async support, it was quite challenging... but after putting in quite some hours, I'm happy to announce that I just completed implementing the complete NIP-47 specification in PHP.

Check out the code at https://github.com/dsbaars/nostr-php-nwc/ and if you're a PHP programmer, please try to use and break the code :)
