Add inscription page

[casey]

It should be possible to:

• Share a URL to an inscription on ordinals.com
• View inscriptions on dedicated pages, instead of at the bottom of the ordinal page

This implies some kind of permalink. I think the easiest thing to base a permalink on is the hash of the transaction in which it appeared. I created issues for inscription names and numbers, which are more complex, and we can worry about those later: #794 and #793.

Question: How do we disambiguate between linking to a transaction and linking to an inscription?

Ideas:

• inscriptions are bech32 encoded transaction hashes with inscription as the human readable prefix
• Inscriptions have the hex characters or bytes reversed
• inscriptions are the hex transaction hash then a slash, then the output number
• inscriptions are the hex transaction hash with the output number encoded as hex

Fixed in #817.
