Plot typing speed throughout the duration of a single test

[MasterMedo]

Create a diagram showing typing speed throughout the duration of a single test. The program logs the time it takes to press each character and the typing speed the character was pressed with. This information is stored in typetest/results/char_speeds.csv. It might look something like this:

character	time to press [s]	speed [wpm]
t	0.1237139701843261	96.99793792181062
w	0.0068349838256835	1755.673503557974
o	0.2604360580444336	46.07656900548177
	0.1182172298431396	101.5080459584663

It would be beneficial if after the typing test is completed, the user is presented with a diagram showing his typing speed throughout the test. This can be added with an option e.g. --plot-wpm.

For reference, here is how this plot looks like on monkeytype.com, the x-axis is the number of characters (character index):
