⚡ refactor tableRuns to better manage memory

[bunop]

Description

tableRuns are now calculated on each chromsome one-by-one. Code was revisited to better manage resources and calculate percentages properly. snpInsideRunsCpp is no more exported, so it's not possible to provide directly its results to tableRuns

Related Issue

closes #31
closes #36

Motivation and Context

tableRuns consume a lot of memory especially when applied to WGS data. By calculating snpInsideRuns on each chromosome and immediately filtering runs lower the memory usage

How Has This Been Tested?

Code has been tested with CI and by manually checking results
