[Feature] Display summary information in very small tty

[Jasha10]

When the terminal is very very small, mprocs does not display useful information. Here are screenshots of mprocs running in very small terminals:

1 character tall:

2 characters tall:

4 characters tall:

6 characters tall:

My suggestion would be to add a special case for handling very small terminals like in the screenshots above.
For example, if the terminal is less than 6 characters tall, mprocs could display text like "3 UP, 2 DOWN" in green/red text at the upper-left corner of the terminal. This would enable users to determine whether their jobs are still running without needing to expand the size of the terminal.
