Add ASCII only mode about termsaver HOT 4 CLOSED

@basxto I actually like how your mind was working with this, so I ran with your technique.

A new PR is up that should do nicely. It may take a bit to get merged in, but the work is done.

Care to elaborate what this functionality is about?

This was especially meant for sysmon.
It would be handy for matrix, but cmatrix is already capable of that.

Background is that I’m writing a little terminal module for LED panels.
I'm very limited on pixels and that’s why I tried to get it working with only ASCII.
But I added ASCII altchars (lineart stuff) and a few characters from unicode (half blocks, lineart) by now.
I still have a few missing characters on sysmon though. (It looks the same on TTY)

Before I started translating unicode characters to altchars, sysmon looked like this:

It could be realized with just ASCII (#_## etc) or with altcodes.
Altchars work like this: \033(0m\033(B for └
A full block could be created with inverting color \033[7m \033[27m

And before I started to tread multiple (ASCII) chars as one unknown unicode character, it looked like this:

That’s how it will look in Terminals, that do not support unicode.

EDIT: I modified my unicode translator a bit and this is how sysmon could look with just +-|#

I could imagine something like this:

    pie_chart = [['○', '◔', '◑', '◕', '●'],[' ', '|', '(', 'C', 'O'],[' ', '|', '(', 'C', 'O']]
    """
    Holds the unicode symbols for pie chart representation of percentage
    """
    block = [[' ', '▁', '▂', '▃', '▄', '▅', '▆', '▇', '█', '█'], [' ', '\033(0s\033(B', '\033(0s\033(B', '\033(0s\033(B', '\033(0s\033(B', '\033[7m \033[27m', '\033[7m \033[27m', '\033[7m \033[27m', '\033[7m \033[27m', '\033[7m \033[27m'], [' ', '_', '_', 'm', 'm', 'm', '#', '#', '#', '#']]
    """
    Holds the block unicode symbolds used to draw the charts
    """
    axis_corner = ["└","\033(0m\033(B","+"]
    """
    Represents the unicode symbol for the axis corner in the xy chart
    """
    axis_h = ["─","\033(0q\033(B","-"]
    """
    Represents the unicode symbol for the horizontal axis in the xy chart
    """
    axis_v = ["│","\033(0x\033(B","|"]
