Forward MTS-ESP tuning to other computers.

MTS-ESP retunes synths running on the same computer. I wanted to retune a synth running on a Raspberry Pi using the MTS-ESP source in a DAW on my laptop.

We can forward the MTS-ESP tuning from the laptop to the Raspberry Pi by running:

• A tuning server on the laptop, which responds to http requests by sending the current MTS-ESP tuning as json.
• A tuning client on the Raspberry Pi, which requests the tuning once per second and updates the MTS-ESP tuning on the Raspberry Pi.

In this way the MTS-ESP source on the laptop and the synth on the Raspberry Pi can use MTS-ESP as normal; they don't need to know they're running on different computers.

This repo provides:

• tuning-server and tuning-client command line programs
• An audio plugin TuningServer.clap which runs the tuning server in a DAW

The CLAP plugin saves manually running the tuning-server CLI program; the plugin automatically starts and stops the tuning server.
