Add python implementation of QuantAmm

[brunoguerios]

Closes #118

Main:

• Add python implementation of QuantAmm maths

Extra:

• Refactor integer division so it follows TS and Solidity behavior (rounding towards zero)

[Copilot]

Pull Request Overview

This PR introduces a Python implementation of the QuantAMM pool and ensures integer division matches TypeScript and Solidity (round‐towards‐zero) behavior.

• Added QuantAMM math, data mapping, and pool logic
• Registered QuantAMM in pool‐state mapper and vault
• Introduced BigInt for zero‐towards‐zero division and updated log‐exp math

• [nitpick] Add a docstring for the QuantAmm class to explain its purpose and public API usage.

class QuantAmm(PoolBase):

python/src/pools/quantamm/quantamm_math.py:6

• [nitpick] Function name uses British spelling (normalised) while other parts use American (normalized); consider unifying spelling for consistency.

• The new on_swap logic for QuantAmm isn't covered by unit tests; consider adding tests for both GIVEN_IN and GIVEN_OUT swap scenarios.

    def on_swap(self, swap_params: SwapParams) -> int:

python/test/utils/map_pool_state.py:11

• The module no longer defines or exports transform_strings_to_ints, but some tests import it. Either add transform_strings_to_ints here or remove its import in tests.

python/test/test_add_liquidity.py:4

• [nitpick] The sys import is unused in this test file; consider removing it to keep imports clean.

import sys

python/src/common/log_exp_math.py:2

• [nitpick] Wrapping every division in BigInt can add significant overhead; consider minimizing conversions or optimizing critical loops.
