pool package

Observe returns the tick and seconds-per-liquidity cumulatives for each requested lookback, matching Uniswap V3's observe(uint32[] secondsAgos). Parameters:

• poolPath: Canonical pool path whose oracle history is queried.
• secondsAgos: Lookback intervals in seconds; one cumulative pair is returned for each value, in the same order.

Returns:

• []int64: Tick cumulative values corresponding to each requested lookback.
• []string: Seconds-per-liquidity cumulative X128 values, serialized as base-10 strings, corresponding to each lookback.
• error: Non-nil when pool or observation data cannot be read.
