Error on winbar highlighting result

[kevinm6]

Hello, thanks for the plugin.
Using it and updated to the last release with luarocks dependency and the other updates I get an error on the result highlight of the winbar.

Due to this part of the code

rest.nvim/lua/rest-nvim/result/winbar.lua

Lines 64 to 69 in 5300ae0

	local hl_fg = string.format("%02X", vim.api.nvim_get_hl(0, { name = name, link = false }).fg)
	if #hl_fg == 5 then
	hl_fg = "0" .. hl_fg
	end
	hl_fg = "#" .. hl_fg
	return hl_fg

when the Hex value of the highlight contains two prefixed zeros (example #00FF87) it doesn’t match to any of the if statement since you’re checking if the chars left after the format are 5, but in this case they are 4.

In the most simple way is enough to do another check and have something like this

  local hl_fg = string.format("%02X", vim.api.nvim_get_hl(0, { name = name, link = false }).fg)
  if #hl_fg == 4 then
    hl_fg = "00" .. hl_fg
  elseif #hl_fg == 5 then
    hl_fg = "0" .. hl_fg
  end
  hl_fg = "#" .. hl_fg
  return hl_fg
