Print consecutive spaces faster

Browse Source 
This commit adds a new function, print_n_spaces(), which prints a sequence of (up to 80) space characters.

This new function is used to replace a few places in testssl.sh in which a sequence of space characters is printed by calling 'out " "' in a loop. The new function is much faster than the current code, so it will make testssl.sh run slightly faster.
