accounts/abi: ABI explicit difference between Unpack and UnpackIntoInterface (#21091)
* accounts/abi: refactored abi.Unpack * accounts/abi/bind: fixed error * accounts/abi/bind: modified template * accounts/abi/bind: added ToStruct for conversion * accounts/abi: reenabled tests * accounts/abi: fixed tests * accounts/abi: fixed tests for packing/unpacking * accounts/abi: fixed tests * accounts/abi: added more logic to ToStruct * accounts/abi/bind: fixed template * accounts/abi/bind: fixed ToStruct conversion * accounts/abi/: removed unused code * accounts/abi: updated template * accounts/abi: refactored unused code * contracts/checkpointoracle: updated contracts to sol ^0.6.0 * accounts/abi: refactored reflection logic * accounts/abi: less code duplication in Unpack* * accounts/abi: fixed rebasing bug * fix a few typos in comments * rebase on master Co-authored-by: Guillaume Ballet <gballet@gmail.com>
