This adds `gojs.WithOSUser` which passes through current user IDs so that GOOS=js compiled wasm can read them. This also adds support for reading back the uid and gid on files. In summary, this passes `os.TestChown` except on windows where it will not work due to lack of support. Signed-off-by: Adrian Cole <adrian@tetrate.io>
