Please add a blue color to the palette

The current `AnsiBlue` is actually purple from the palette, which is too different to be considered "blue".
Please consider adding a blue-ish color to the [standard](https://spec.draculatheme.com/#sec-Standard) palette, or at least use a proper blue for [blue](https://spec.draculatheme.com/#AnsiBlue) and [bright blue](https://spec.draculatheme.com/#AnsiBrightBlue) ANSI colors.
See https://github.com/dracula/visual-studio-code/issues/166
> terminals do have the concept of "blue" [...] Terminals are generic. Any kind of program can run in them. I gave the `ls` example (which bothers just because I'm used to blue for folders), but other programs may run where "blue" isn't a code for representing some other concept - it really means "a blue color".

NOTE: depending on the blue you choose, you might want to tweak ANSI cyan as well so that the purple/blue/cyan contrast is consistent (not too much or too little) with the contrast in the default colors you usually find in terminals (e.g. Ubuntu bash).

Just an example, `#666ce8` is a blue that's still kind of close to purple

You can also take bats, halloween or dracula as an inspiration, for example:
