Allow odin run - -file

[mks]

Current behaviour:

❯ cat <<EOF | odin run - -file
package main

import "core:fmt"

main :: proc() {
        fmt.println("Hellope!")
}
EOF

Error: Expected either a directory or a .odin file, got '-'

It would be nice if it worked.

[laytan]

A similar thing that would be nice is allowing odin run -file path/to/file.odin which would make shebangs work:

#!/usr/bin/env odin run -foo -bar -file

package main

import "core:fmt"

main :: proc() {
    fmt.println("Hellope")
}

Would allow running it with:
$ ./path/to/file.odin

And/or allow leaving out the .odin for the main file which makes it:
$ ./path/to/file
