Option to override extensions?

[kaushalmodi]

Hello,

I am not a Rust programmer but I was following the CONTRIBUTING/md to add support for Verilog and SystemVerilog.

So I added these to the languages.json (in alphabetical order):

        "SystemVerilog":{
            "base":"c",
            "extensions":[
                "sv",
                "svh"
            ]
        },

        "Verilog":{
            "base":"c",
            "extensions":[
                "v",
                "vg"
            ]
        },

But then on building, I get:

   Compiling tokei v6.0.0 (file:///home/kmodi/downloads/git/tokei)
error[E0001]: unreachable pattern
   --> /home/kmodi/downloads/git/tokei/target/x86_64-unknown-linux-musl/release/build/tokei-cfa6d5ef49951a7c/out/language_type.rs:875:25
    |
875 |                         "v" |
    |                         ^^^ this is an unreachable pattern

error: aborting due to previous error

error: Could not compile `tokei`.

I believe it's because the .v extension is already taken by Coq:

        "Coq":{
            "base":"func",
            "extensions":[
                "v"
            ]
        },

I have never coded in Coq.. So would there be a way to add a smarter detection of languages.. based on some language keywords may be? Or simply config options?

Another such conflict with

        "ObjectiveC":{
            "name":"Objective C",
            "base":"c",
            "extensions":[
                "m"
            ]
        },

All my .m files are Matlab scripts.. makes more sense.. m for Matlab :)
