Visible Offhand

• Added configuration option "handheldItems", the default is "minecraft:filled_map", can be filled in a new value (id:item) to tell the Mod that the main hand holding these items will not force Offhand rendering

//The default content in the "visible_offhand.json" configuration file:
{
  "doubleHands": true,
  "handheldItems": [
    "minecraft:filled_map"
  ]
}

• Replace the "Done" button in the Mod configuration screen with the "Reload Profile/Done" button, you can re-read the configuration information in the configuration file at any time while the game is running
• Add a new client-side command, /visibleoffhand reload, to re-read the configuration information from the configuration file
