Investigate performance issues

The leading theory is that the move to JSON serialization caused the performance degradation. We first need to revert to the old binary format to prove that theory.

Once proven, compare the following formats:

• JSON (as is today)
• Old binary format
• ASN.1 (built in to MASL code generator already)
• Various binary formats supported by nlohmann_json

Consider which format is best. Consider making this a per-topic configuration

A test build was created (4.4.6-binary). Compared to the latest release build 4.4.5, no performance difference was observed in initial tests.

After testing with different versions of docker, it was observed that using docker engine v26.0 produces about twice the performance compared to using docker engine v26.1
