Uniswap V3 Position Manager

Reads a V3 position NFT and converts its tick bounds into real prices, undoing the decimal difference between the two tokens — skip that and the price is wrong by orders of magnitude. Shows fee tier, liquidity and uncollected amounts, and explains that tokensOwed only updates when the position is touched, so a long-untouched position can show zero while having earned plenty. Carries no hardcoded manager address. The manager address is yours to supply, since deployments differ per chain. Uncollected fees read from tokensOwed only update when the position is touched, so a long-untouched position can show zero while having earned plenty. A position earns nothing at all while price sits outside its range.
