Refactored cmd2 to better account for our use of Rich.

* Added string_utils.py which contains all string utility functions.
  This includes quoting and alignment functions from utils.py.
  This also includes style-related functions from ansi.py.

* Added colors.py which contains all color names supported by Rich.

* Added styles.py which contains the names of all cmd2-specific styles.

* Moved string styling functionality from ansi.py to string_utils.py.

* Removed all text style Enums from ansi.py since we use Rich.

* Renamed ansi.py to terminal_utils.py to reflect the functions left in it.

* Removed table_creation.py since we use Rich tables now.

     - No longer setting parser's `prog` value in `with_argparser()` since it gets set in
       `Cmd._build_parser()`. This code had previously been restored to support backward
       compatibility in `cmd2` 2.0 family.
+    - Removed `table_creator` module in favor of `Rich` tables.
 
 - Enhancements
     - Simplified the process to set a custom parser for `cmd2's` built-in commands. See
