BREAKING CHANGE: modifying the default options for keymaps and autocmds
is now done by overwriting them, since they won't be loaded into the
global `lvim` table anymore
* refactor: use the lua-commands api
* refactor!: use the lua-autocmds api
* fix(settings): let neovim handle spellfile
* feat: add log:set_log_level()
* chore: update examples
* chore: add deprecation notice for custom_groups
* refactor: use api-autocmds for lsp functions
* chore: use the existing client.supports_method api
* fix: a callback in an autocmd doesn't pass nil
* revert: keep changes minimal to which-key
