Calculate the INIT_CODE_HASH of a smart contract bytecode (needed for CREATE2 address computation).
node src/calc.mjs
The example in src/calc.mjs uses the contract creation bytecode of SpooksySwap Pairs (which is deployed with the createPair method of the Factory).
You can compare the console output with the INIT_CODE_HASH in the SpookySwap SDK: https://github.com/SpookySwap/spookyswap-sdk/blob/master/src/constants.ts#L26
