Made double parsing culture invariant for opencover format

[pamidur]

The problem

On machines with non-US culture the app fails with an exception:

Unhandled Exception: System.FormatException: Input string was not in a correct format.
   at System.Number.ParseDouble(ReadOnlySpan`1 value, NumberStyles options, NumberFormatInfo numfmt)
   at Codacy.CSharpCoverage.Parsing.Processors.OpenCoverProcessor.Parse(String file)
   at Codacy.CSharpCoverage.Program.<>c.<Main>b__0_0(Options opt)
   at CommandLine.ParserResultExtensions.WithParsed[T](ParserResult`1 result, Action`1 action)
   at Codacy.CSharpCoverage.Program.Main(String[] args)

The solution

Make double parsing culture invariant
