Add support for Protocol Buffers binary encoding as an alternative to JSON
for OTLP trace, metrics, and log exports. This enables more efficient
wire format when communicating with OpenTelemetry collectors.
- Add `protocol` option ("json" | "protobuf") to Otlp.layer and individual
OtlpTracer, OtlpMetrics, OtlpLogger layers
- Implement protobuf wire format encoding following opentelemetry-proto specs
- Set appropriate Content-Type header (application/x-protobuf vs application/json)
- No new dependencies - protobuf encoding implemented from scratch

Description
Add support for Protocol Buffers binary encoding as an alternative to JSON for OTLP trace, metrics, and log exports. This enables more efficient wire format when communicating with OpenTelemetry collectors. In particular, some OTLP collectors, such as Coralogix, only support protobuf and not json.
