Mihai Parparita 2f702b150e cmd/tsconnect: add dev-pkg command for two-sided development
Allows imports of the NPM package added by 1a093ef482
to be replaced with import("http://localhost:9090/pkg/pkg.js"), so that
changes can be made in parallel to both the module and code that uses
it (without any need for NPM publishing or even building of the package).

Updates #5415
