Create a parser to convert Vimscript keymaps into legendary tables

[mrjones2014]

Theoretically we should be able to parse a Vimscript keymap in the form:

vnoremap <leader>t :DoSomethingWithLeaderT<CR>

and convert that into the equivalent legendary keymap table:

{
  '<leader>t',
  ':DoSomethingWithLeaderT<CR>',
  mode = 'v',
  opts = {
    noremap = true,
  },
}

We would need to take into consideration all the different options and types of mapping commands in order to set all the right options on the table.
