Instead of taking binary string literals, take string ones instead,
making it easier for users to define a module, i.e. instead of
calling `module!` like:
module! {
...
name: b"rust_minimal",
...
}
now it is called as:
module! {
...
name: "rust_minimal",
...
}
Module names, aliases and license strings are restricted to
ASCII only. However, the author and the description allows UTF-8.
For simplicity (avoid parsing), escape sequences and raw string
literals are not yet handled.
