📚 Description

This PR adds a new syntax to allow http method to be matched with radix3.

    const router = createRouter();
    router.insert({ path: "v2", method: "GET", payload: { path: "v2" } }); //v2 syntax
    router.insert("v1", { path: "v1", field: 1, anotherField: 2 }); //v1 syntax

The current implementation contains a (small) breaking to staticRoutesMap, which is now a 2 dimensional array to support fast method matching. A one dimensional approach is possible, but not as robust as the 2 dimensional one https://github.com/unjs/radix3/pull/59#discussion_r1278317571.

@pi0 Refactored according to your instructions, added benchmarks and more tests.

@pi0 Just revisiting this PR. I simplified it, rebased and added a description, as well as flagged it as a breaking change due to the staticRoutesMap change.

Put a pending label i need to still benchmark and validate it more.
