Logger fallback to console.error if process._rawDebug is missing

[nickg]

When running under Deno instead of NodeJS I get the following stack trace when the native extension is loaded:

N-API call failed: napi_create_threadsafe_function( env, node_rawdebug, NULL, resource_name, 0, 1, ctx, s_threadsafe_log_finalize, ctx, s_threadsafe_log_call, &ctx->log_drain)

Deno does not provide console._rawDebug so fall back to console.error instead.
