The message format optimisation currently has a number of low hanging fruits:

Of the ones above, compression seems to be the most straightforward one to try.

Based on 10k message samples collected from filecoin/46 network, it looks like zstd compressed messages are on average 60% smaller. (min/max compression message reduction: 7.4% and 69%).

Compressing messages is therefore worthwhile indeed.

Experiment with compressing GPBFT messages and certs
1fb2158 
Modify observer to report space gain by compressing GPBFT messages using
zstd.

Add a compression test that measures space gain in compressing generated
finality certificates.

The results run on `filecoin/46` passive testing show that compressing
GPBFT messages gain ~60% in space saving.

The latest captured so far:

```
messages observed so far: 37648
Min compression gain: 7.4 %
Max compression gain: 69.0 %
Avg compression gain: 57.3 %
```

Relates to: #757
