fix: Add some type definitions

[hwwi]

Sorry about frequently open a PR.
But createMatchEnhancer was bothering me 😫

No, thank you for adding these!

If it's not too much to ask, would you mind adding a server/test.tsx analogous to https://github.com/4Catalyzer/found/blob/6f55794da28f1ef265d24502b426912f38ff48a1/types/test.tsx just to demonstrate the type definitions in action?

It will also keep us from accidentally breaking stuff.

First, Sorry for my poor English.

I think that getFarceResult function's return type is not Discriminated Unions, so infer is hard.

So I used it this way...

interface FarceResult {
    status?: number;
    element?: React.ReactElement;
    redirect?: {
        url: string;
    };
}

For the time being, I have excluded it from writing test code.
If you decide the direction, I will write continue.

Any comments or thoughts on this?

Sorry for the delay. I'll try to look at this and 4Catalyzer/farce#175 today.
