Sparkplug B to OpenTelemetry Metrics using mochi-co/mqtt

[jmacd]

Here's an implementation of the Sparkplug B specification that passes data into an OpenTelemetry Collector receiver for sending metrics to any one of its supported exporters (e.g., OTLP, Prometheus).

For my tiny application, the entire system is a passive monitoring solution, so no primary SCADA application. The easiest route was for the metrics collector to self-host a mochi-co/mqtt broker.
