[TODO] - Perf Tests: OSC Writing

[stella3d]

There's a few optimizations to be made in the way OscWriter does some serialization (mostly copying multiple bytes at once when serializing strings & addresses)

However, since you should always measure before trying to optimize, a performance benchmark is needed before we can optimize.

Add 2 Tests

Both tests should be parameterized to try with messages of different address and element lengths.

1. A micro-benchmark that just tests the currently most relevant part of serialization, string elements & addresses
2. An integration test that sends messages like a user would, using full messages.
