`Merge-JaCoCoReport`: Calculates hit count correctly?

[johlju]

Problem description

Currently the hit count is overwritten when the merge document's <line> has a hit count higher than the original document's <line>:

https://github.com/gaelcolas/Sampler/blob/02cc8da49a8d837f48c167db56c1ace18fdb5bef/Sampler/Public/Merge-JaCoCoReport.ps1#L89-L96

But shouldn't the hit count of the merge document be added to the count of the original document?

Example:

  Original ci = 1
     Merge ci = 2

        Result: 3

And shouldn't it always add to the hit count, not just when original line is less than the merge line?

Example:

  Original ci = 1
     Merge ci = 1

        Result: 2

This is also true for missed hit count that can be more than 1.

Example from the project SqlServerDsc and the DSC resource SqlAg (DSC_SqlAg.psm1):

<line nr="300" mi="3" ci="0" mb="0" cb="0" />
<line nr="301" mi="1" ci="0" mb="0" cb="0" />
<line nr="303" mi="2" ci="0" mb="0" cb="0" />
