[AIS] Fix plenty of small bugs unveiled by aishub test campaign.

A test campaign was run with live data from aishub.net (ca. 25 millions
sentence, 1.2 GB of logs), the goal was to check the decoding and the JSON
parsing and dumping code.
On all the AIS data, the following tests were done:
- AIVDM decoding
- JSON scaled dump
- JSON validity check on scaled dump.
- JSON unscaled dump
- JSON validity check on unscaled dump
- JSON unscaled idempotency check
- JSON unscaled/scaled idempotency check

The last check consisted of:
- parsing the unscaled dump
- dumping it back in scaled mode
- compare it with the original scaled dump.

This test campaign has unveiled plenty of small bugs all around the AIS code.
This patch fixes all of them and adds new sentences in the regression tests.
