tests: add univ3 svg generation test

[enitrat]

Time spent on this PR: 1d

Adds Mock UniswapV3 contracts that allow querying a dynamically generated on-chain SVG representing a position.
The values are mocked, and due to some issues, the base64 encoding of the image crashes with a stack underflow error (tbd).

However, the encoding of the rest takes ~27M steps

Also: Because NFTDescriptor is a library with an external function, it must be deployed and called with its address. When referring to this library, the compiler will add a placehold in form __$HASH_OF_PATH$__ in the compiled bytecode. Thus, I implemented a way of linking a library in the deployments scripts - we can deploy the contract providing a set of required libraries, that are deployed, hashed, and their address replaces the hash in the compiled bytecode.

good to merge, can ignore the trunk check

I'd revert the changes made to deploy and use the foundry file to get if there are some

    "linkReferences": {
      "solidity_contracts/src/UniswapV3/NFTDescriptor.sol": {
        "NFTDescriptor": [{ "start": 3038, "length": 20 }]
      }
    }

and if so, then deploy them first, and replace. Even the compute_library_identifier doesn't seem required

From where this init code hash was taken ?
Did not find it in commit history of https://github.com/Uniswap/v2-periphery/blob/0335e8f7e1bd1e8d8329fd300aea2ef2f36dd19f/contracts/libraries/UniswapV2Library.sol#L24

[enitrat]

run forge build, open UniswapV2Library.json and take the keccak hash of the bytecode hexstring
