Add liquidity calcs for getting alpha and liquidity amounts given an …

[0xcacti]

Description

This PR adds two new auxiliary functions to calculate liquidity amounts for Uniswap V3-style liquidity provision:

1. get_tao_based_liquidity: Calculates the Alpha amount and liquidity given an amount of TAO and a price range
2. get_alpha_based_liquidity: Calculates the TAO amount and liquidity given an amount of Alpha and a price range

These functions enable users to determine the correct token quantities when providing liquidity within specific price ranges, handling different scenarios based on the current price relative to the range (within range, above range, below range).
