Vary the "DELETE ME" text minimum offset distance with the difficulty level

Currently the offset is fixed if the user set the vim_be_good_delete_me_offset config.

Otherwise the offset is 5 + a random number as seen bellow:

        if (isDefindedUserOffset) {
            offset = Number(
                await game.nvim.getVar("vim_be_good_delete_me_offset"),
            );
            console.log("delete-round#getColumnOffset - userOffset ", offset);
        } else {
            offset = Math.floor(Math.random() * (40 - 5)) + 5;

What if instead we had something like:

var minOffset = {noob: 0, easy: 3, medium: 5, hard: 10, nightmare: 15, tpope: 30};

            offset = Math.floor(Math.random() * (40 - 5)) + minOffset[game.difficulty];

Sorry, I miss the point when you mention it in my MR.

I think is a very good idea especially if you can set vim_be_good_delete_me_random_offset regardless of the difficulty because I play a lot in practice mode and I would love to have the ability to change random_offset.

Yeah, I want this too! Part of the re-thinking would be to reduce the required instructions by going to Lua and thinking about all these things earlier on in the prrocess. Unfortunately I don't know lua at all, so the code will suck :)
