Fixes:

• Optimized to try for all Hosts: Fixed a bug to ensure all hosts are tried for file shard storage.

Improvements:

• BIP39 Key Generation: Default key generation updated to BIP39. An existing Secp256k1 TRON private key can still be imported by running btfs init -i <secp256k1 private key>.
• Unit Update to microBTT: Previously all BTT denominations were in units of Just. This is now updated to micro-BTT.
