Default naming convention for WIT package is broken on Windows (includes a semicolon) #182
Description
Trying to build WIT packages on Windows requires setting the output file name manually via -o/--output, as otherwise wkg creates a blank file named after the namespace. This is due to Windows' file name convention, which doesn't allow certain characters, including semicolons.
Could a different default naming convention be used instead for build files? Like treating the namespace as a directory and storing all of the namespaced packages inside it? Or change the semicolon to a character that is cross-platform friendly like --, _ or +?
