Protobuff definition is not correct

The specification for protobuff states that this record is Varint Encoded.

So it means that it's not guaranteed to have 8 bits. If the field index has its last significant bit on 1 then another byte has to be read.

I've tested this in real life payloads and I've confirmed that it's failing.

This issue should probably be closed since it's a dupe of #152, which describes the exact same problem.
