Theprimeagen's Harpoon Plugin Is Dead, So I Saved It

Hey, thanks for taking inspiration from my plugin! If you ever want to port the feature so no-neck-pain.nvim natively supports harpoon buffer I could help you with the contribution!

With inspiration from shortcuts/no-neck-pain.nvim (hence the branch name), Harpoon menu now has a sidebar mode, which acts as a padding window that persists on the left side of your screen, and shift your main screen to the center and save your neck.

- With ThePrimeagen/harpoon, you open a popup menu, select the file you want, and boom you're there. But what if you want to persistent the menu on screen because you can't remember which file is at which harpoon index?

- At the same time, you want no more neck pain from looking at your screen at a 45 degree angle to write codes for hours. So you have yet another plugin to solve this issue.
