Auto-subscribe from URL params

[DenisCarriere]

Having the user provide all the subscribe payload in the URL, allows the user to do both:

• Connect to WebSockets
• Subscribe based on params

Example:

ws://localhost:3000/subscribe?chain={CHAIN}&moduleHash={MODULE_HASH}

ws://localhost:3000/subscribe?chain=polygon&moduleHash=0a363b2a63aadb76a525208f1973531d3616fbae

Updated to (drop /subscribe):

ws://localhost:3000?chain={CHAIN}&moduleHash={MODULE_HASH}
