v1.2.0+evm

In addition to QoL improvements, this release adds support for including a custom payload with NTT transfers. The custom payload can be set on the source chain by overriding _prepareNativeTokenTransfer, and can be handled on the destination chain via _handleMsg and/or _handleAdditionalPayload.
