Several improvements for performance and future upgradeability of the OPI

[samedcildir]

• The old version tracked 2 hops for every JSON&Text inscription. With this version we added optional configuration to ord to track different types of inscriptions with different hop counts. This was needed since brc20-swap implementation uses several kinds of inscriptions with more than two hops.
• Added original_ticker tracking to brc20
• Implemented self-mint proposal (https://github.com/brc20-devs/brc20-proposals/blob/main/bp04-self-mint/proposal.md)
• Implemented burn proposal (https://github.com/brc20-devs/brc20-proposals/blob/main/bp05-burn/proposal.md)
• Improved the performance of brc20 indexing by around 6x via using batched inserts.

This version changed brc20 hash calculation method due to added new fields. This version added new information to main index db so a full reindex will be needed after update
