Provide a lua API instead of a string command about dial.nvim

[rudenkornk]

Oh, never mind, I figured that out. I just have to use expr = true. In my nvchad-based config it looks like this:

M.dial = {
  n = {
    ["<C-a>"] = {
      function()
        return require("dial.map").inc_normal()
      end,
      opts = { expr = true },
    },
    ["<C-x>"] = {
      function()
        return require("dial.map").dec_normal()
      end,
      opts = { expr = true },
    },
  },
  v = {
    ["<C-a>"] = {
      function()
        return require("dial.map").inc_visual()
      end,
      opts = { expr = true },
    },
    ["<C-x>"] = {
      function()
        return require("dial.map").dec_visual()
      end,
      opts = { expr = true },
    },
    ["g<C-a>"] = {
      function()
        return require("dial.map").inc_gvisual()
      end,
      opts = { expr = true },
    },
    ["g<C-x>"] = {
      function()
        return require("dial.map").dec_gvisual()
      end,
      opts = { expr = true },
    },
  },
}
