Fix .cov file format

[adrienbrault]

I was trying to phpcov merge 2 ~10MB .cov files generated by this package, and noticed it was suspiciously slow: ~3mn.

Now that the .cov files are generated using SebastianBergmann\CodeCoverage\Report\PHP, phpcov merge takes ~4s.

Very interesting, and nice to hear from you again, Adrien!
Do you have some kind of explanation for this improvement? I'll merge anyway, but I'm just curious.

Released as v1.5.0

Here's the beginning of a .cov prior to this patch:

<?php return unserialize('O:43:"SebastianBergmann\\CodeCoverage\\CodeCoverage":15:{s:51:"' . "\0" . 'SebastianBergmann\\CodeCoverage\\CodeCoverage' . "\0" . 'driver";O:48:"SebastianBergmann\\CodeCoverage\\Driver\\PcovDriver":3:{s:56:"' . "\0" . 'SebastianBergmann\\CodeCoverage\\Driver\\PcovDriver' . "\0" . 'filter";O:37:"SebastianBergmann\\CodeCoverage\\Filter":2:{s:44:"' . "\0" . 'SebastianBergmann\\CodeCoverage\\Filter' . "\0" . 'fil

After:

<?php
return \unserialize('O:43:"SebastianBergmann\CodeCoverage\CodeCoverage":15:{s:51:"�SebastianBergmann\CodeCoverage\CodeCoverage�driver";O:48:"SebastianBergmann\CodeCoverage\Driver\PcovDriver":3:{s:56:"�SebastianBergmann\CodeCoverage\Driver\PcovDriver�filter";O:37:"SebastianBergmann\CodeCoverage\Filter":2:{s:44:"�SebastianBergmann\CodeCoverage\Filter�files";a:1627:{s:33:"/application/src/App/.preload.php";b:1;s:67:"/application/src/App/A

So I'm assuming that the performance issue was related to the all the string concatenation/etc.

That makes sense, thanks!
