Set Cursor Style (DECSCUSR)

If n is omitted, n defaults to 0. n must be an integer between 0 and 6 (inclusive). The mapping of n to cursor style is below:

n	style
0	terminal default
1	blinking block
2	steady block
3	blinking underline
4	steady underline
5	blinking vertical bar
6	steady vertical bar

For n = 0, the terminal default is up to the terminal and is inconsistent across terminal implementations. The default may also be impacted by terminal configuration.
