Support for simultanious scroll and centering

[JulianGodd]

I usually map zz after <c-b> and <c-f> but doing this with neoscroll causes these behaviors to happen one after another.

I was able to get the desired functionality with the following, but it's a bit hacky:

vim.keymap.set({'n', 'v'}, '<c-b>', '<cmd>lua vim.api.nvim_command("normal " .. vim.api.nvim_win_get_height(0)-5 .. "k"); require("neoscroll").zz(220)<cr>')
vim.keymap.set({'n', 'v'}, '<c-f>', '<cmd>lua vim.api.nvim_command("normal " .. vim.api.nvim_win_get_height(0)-5 .. "j"); require("neoscroll").zz(220)<cr>')

Perhaps a by default false bool on the scroll action could enable centering?

Thanks for this awesome plugin

I agree, this would be a nice option to have out of the box.
The solution by @JulianGodd did not work for me, so I solved it using the post_hook.

require('neoscroll').setup({
  post_hook = function(info) if info == 'centercursor' then vim.cmd('normal! zz') end end,
})
local t = {}
t['<C-u>'] = { 'scroll', { '-vim.wo.scroll', 'true', '350', 'sine', [['centercursor']] } }
t['<C-d>'] = { 'scroll', { 'vim.wo.scroll', 'true', '350', 'sine', [['centercursor']] } }
require('neoscroll.config').set_mappings(t)

Isn't a better solution to bring the cursor to the middle of the window with <S-m> before scrolling?

Also this is a duplicate of #65 so closing this one.
