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.

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

Better yet, deprecate -file. I know my file is a file, not a directory; and Odin knows my file is a file, not a directory... so why should I tell Odin my file is a file, not a directory?

Sometime ago I was told that -file has no technical reason, but it's just a "social" option. I understand the rationale but I think it's a non-problem. Every time I have to write -file I feel as if I were writing -lang:odin :-) Also, when I have encouraged other people to try Odin, they were surprised by that unnecessary option and usually forgot to use it during their initial tries.
