Phoenix Bonds v0.1.0

This is an internal release that marks the version that is ready for auditing and testnet testing, which includes major features in Phoenix Bonds:

1. Bond: user bonds $n$ NEAR, and create a new bond note with bonding amount set to $n$
2. Cancel: user cancels a bond with amount $n$, and receives LiNEAR with value equals to $n$ NEAR
3. Commit: user commits a bond note with amount $n$ NEAR to receive pNEAR minted for her/him
4. Redeem: user redeems $p$ pNEAR, and will receive LiNEAR based on the pNEAR redemption price.
