This release includes a ton of performance and stability improvements!

NUTs:

• Dynamic change output amounts (NUT-08 update)

Mint:

• Use httpx library instead of requests for asynchronous operations
• Transition from using DB locks to asyncio locks (for compatibility with RaspberryPi systems and LNbits)

Wallet:

• Huge performance increase thanks to db optimizations
• Multimint swaps in Nutshell! Enter cashu swap or use the wallet API.
• Option to mint tokens of a specific denomination (for headless operation)
