Add a decimal place to Pause property (milliseconds)

Currently the Pause property of a Caesura is set in one-hundredths of a second, two decimal places. I would like to increase it to 3 decimal places, which is millisecond precision, which is useful in various contexts. I can prepare a pull request easily and at any time, but I wanted to start the ball rolling here.
Let me know if I can create the PR immediately or if it would be better to wait. I assume there is no opposition to this, but if there is, tell me what it is.
