This commit adds a "--no-check" option to following subcommands: - "deno cache" - "deno info" - "deno run" - "deno test" The "--no-check" options allows to skip type checking step and instead directly transpiles TS sources to JS sources. This solution uses `ts.transpileModule()` API and is just an interim solution before implementing it fully in Rust.
