go-proio: Event corruption with large LZ4 buckets

[decibelcooper]

Identified by protobuf errors (wrong wiretype and field id). Saw this when simulating and digitizing high-energy events and keeping all calorimeter eic::SimHits. Events were on O(10 MB) each, uncompressed. It seems to be an issue with the github.com/pierrec/lz4 reader when decompressing these large frames, but I can't be sure yet.
