Complete Tor Support

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Koios does not have Tor support either via an onion or the api. Users querying, simulating, and submitting transactions from privacy-preserving protocols could potentially have their IP leaked via the Koios API. It's the final piece of the puzzle for privacy dapps.

Describe the solution you'd like
A clear and concise description of what you want to happen.

We need the ability to visit the onion, get an API key for TOR use from the onion, and allow users to query, simulate, and submit transactions over Tor. Best case, do not force wallet registration for the API key for this feature. Just ban the key if it gets rate-limited or has too much spam. Wallets do not currently work on Firefox so Tor access will be very limited. Worst case, force users to the clearnet site and connect via some wallet to get the key. The goal here is getting Tor to work and having users being able to use it. I just rather prevent the IP to API key link as much as possible.

Blockfrost does it but I rather use Koios.
