Added support for prettier_d_slim

[asifZaman0362]

No prettierd on NixOS and prettier is slow so added support for prettier_d_slim which happens to be even faster than prettierd.

Does this support Prettier cli flags?

Lines 152 to 190 in d98e732

	You can set [Prettier's options](https://prettier.io/docs/en/options.html) too.
	They are passed to the `prettier` CLI.
	```lua
	prettier.setup({
	cli_options = {
	arrow_parens = "always",
	bracket_spacing = true,
	bracket_same_line = false,
	embedded_language_formatting = "auto",
	end_of_line = "lf",
	html_whitespace_sensitivity = "css",
	-- jsx_bracket_same_line = false,
	jsx_single_quote = false,
	print_width = 80,
	prose_wrap = "preserve",
	quote_props = "as-needed",
	semi = true,
	single_attribute_per_line = false,
	single_quote = false,
	tab_width = 2,
	trailing_comma = "es5",
	use_tabs = false,
	vue_indent_script_and_style = false,
	},
	})
	```
	By default these options are only used if prettier config file is not found.
	If you want to change that behavior, you can use the following option:
	```lua
	prettier.setup({
	cli_options = {
	-- https://prettier.io/docs/en/cli.html#--config-precedence
	config_precedence = "prefer-file", -- or "cli-override" or "file-override"
	},
	})
	```

Looks like prettier_d_slim does not support --config-precedence=prefer-file. Created a PR:
