v2.15.0

Added

• EthereumFlow
• EthereumTransactionData
• EthereumTransactionDataLegacy
• EthereumTransactionDataEip1559
• Signer.getAccountKey() - Signature providers should be implementing this method, but
  it was added in a none-breaking change way so old signer provider implementations won't
  break when updating to the latest JS SDK version
• ContractCreateFlow.executeWithSigner() - Execute a flow using a signer
• AccountInfoFlow.verify[Signature|Transaction]WithSigner() - Execute a flow using a signer
• A third party time source will be used for transaction ID generation when possible.

Deprecated

• EthereumTransaction.[set|get]CallData() - Use EthereumTransaction.[set|get]CallDataFileId() instead
• EthereumTransaction.[set|get]MaxGasAllowance() - Use EthereumTransaction.[set|get]MaxGasAllowanceHbar() instead
