Progress precision

[quasipickle]

For long running progress bars, seeing it sit at 1% isn't exciting, so I added the ability to change the precision of the percentage.

Usage is straightforward:

$progress = $this->cli->progress(3);
$progress->precision(3);
$progress->current(1);

===>         33.333%

I tried to write a test, but I'm not well versed in unit-testing so this causes an error I'm not sure how to fix:

vendor/bin/phpunit --filter it_can_output_a_progress_bar_with_precision tests/ProgressTest.php
