Compatibility with latest drcov

[Semnodime]

Since the last commit of CutterDRcov, drcov has updated and drcov log files now have a new version.

Please add compatability with the latest drcov. The log file format might have changed only little making the implementation of a parser for the latest drcov straightforward.

DRCOV VERSION: 3
DRCOV FLAVOR: drcov-64
Module Table: version 5
