Fix https://github.com/NvChad/nvim-colorizer.lua/issues/12 | Add support for tailwind colors

Three methods

normal: Use the hardcoded colors

lsp: Use lsp to fetch colors

both: Use the hardcoded colors and use lsp too if available

although this is hardcoding, but working with what we got, has all the
colors tailwind provides, atleast the prebuilt ones

for new defined colors, have to enable the lsp method

Generated using https://github.com/tailwindlabs/tailwindcss/raw/master/src/public/colors.js
and https://github.com/tailwindlabs/tailwindcss/raw/master/src/corePlugins.js

use a different namespace than default for tailwind lsp method

only try to use lsp method if attached

Misc changes

  export the user_default_settings to doc

  clear name space after the lines are processed for a smooth transition

  cleanup some code
