Is your feature request related to a problem? Please describe.

When I close Neovim, the view is lost. I often edit a view using delete (dd), or trouble_add

trouble.nvim/lua/trouble/sources/snacks.lua

Line 110 in 85bedb7

trouble_add = { action = M.wrap({ type = "smart", add = true }), desc = "smart-add-to-trouble" },

The view act as my to-do list. But noevim crash some time, so the editions made to the view are lost.

Describe the solution you'd like

An API like require("trouble").save(filename, opts) to save a view to a file.

Describe alternatives you've considered

Use quickfix list with romainl/vim-qf plugin. But it is hard to keep it in sync with trouble.
