CLI bug fixes, improvements, and color

[m4b]

WIP

1. Adds color 😻 to asm in CLI
   

2. Moves the CLI display logic to CLI module

3. Fixes longstanding bug incorrectly resolving call to internal, resolved functions, and now correctly displays name, e.g.:
   

4. Correctly resolves multiple function aliases, e.g., printf, _IO_printf in libc

5. Adds a new 2x faster pipeline which updates the program object automatically, and uses rayon for parallelism when no UI thread will be present (so CLI uses it)

6. Adds a function iterator to program for ergonomics

7. some touchup and love to the program object

8. Add region() method to project, so clients don't need to import graph-algos to use project

NOTE: we should switch eventually to either term or termcolor to be more friendly (e.g., not print garbage) to window machines, as well as when piping to a file

Wow, fancy! 😍

(e.g., not print garbage) to window machines, as well as when piping to a file

We can always fix things Later™️

It's not like people use windows that much anyway ;)

I actually already find syntax highlighting for asm output indispensable. Helped find and fix call function bug, as well as highlighting the semantic differences, e.g. je in x86 as well as how leaq is treated

Coverage decreased (-0.1%) to 59.812% when pulling faec0ef on m4b/cli_color into c738b31 on master.

👍 Amazing work as usual

@m4b does the highlighting work under Windows as well?

[m4b]

No :/ need to add term or termcolor crate for better cross platform printing. shouldn't be too hard
