ProtobufRuntime issue, possibly when decoding array of int32

[lightyear15]

Please refer to the bug reported in repository:
https://github.com/lightyear15/sol-protobug

As explained in the README, it looks like it might be something related to the repeated int32 field.

Thanks for this report!
I investigated this issue and finally noticed that the current implementation of solidity-protobuf cannot decode packed repeated fields at all.
In proto3, repeated fields of scalar numeric types are packed by default.

(For packed repeated fields, see https://developers.google.com/protocol-buffers/docs/encoding#packed)

In fact, I passed your test by adding [packed=false] to L57.

@lightyear15 This is still an issue and should be fixed at some point, but can you use this workaround ([packed=false]) at this point?

Thanks a lot @siburu ,
The protobuf message definition are not under my control.
I can try to push for review the change and see what maintainers have to say about.
I will mention this Issue ticket and see what they think about this
In the meantime: thanks a lot.
