add updated configurations for new chains

[CluEleSsUK]

All checks now pass.

The DCIPHER_PUBLIC_KEY has been switched over to the new one which is used on all chains that support user billing.

The integration tests for the chains that do not support user billing yet, have been commented out temporarily.

Function calculateRequestPriceNative has been added to help users estimate how much their request will cost based on the callbackGasLimit and the current chain gas price (used by the RPC provider by default when not specified). This function is also used in the requestRandomness logic.

async calculateRequestPriceNative(callbackGasLimit: bigint): Promise<bigint> {
      const requestPrice = await this.contract.calculateRequestPriceNative(callbackGasLimit)
      return requestPrice;
  }

calculateRequestPriceNative returns a better estimate compared to calling RandomnessSender.estimateRequestPriceNative(uint32 _callbackGasLimit, uint256 _requestGasPriceWei)) and passing in a hardcoded network gas price which could be lower than the current network gas price and will give the user a lower estimate compared to calculateRequestPriceNative and in some cases could lead to a fee too low revert message from BlocklockSender. @CluEleSsUK

@CluEleSsUK All the tests should be good now.
Filecoin calibration testnet is still running the JS agent and will be switched over soon.
Filecoin tests are commented out.
