Improvements for Typescript

[JohT]

🚀 Feature

• Support symbolic links when detecting changed files.
• Compare Typescript scans in separate path finding plots. Now, you can not not only compare the max. shortest and longest paths of Typescript packages, but additionally also the scans (e.g. repositories) that contained them.
• Add exploratory queries for longest shortest path and max. longest path.. Now, there are additional queries to manually explore results of "all pairs shortest path" and "longest path" algorithms.
• Add package json dependencies to external dependencies report. Now, there are additional CSV reports for external dependencies focussing on the dependencies declared in package.json files including their versions and which dependencies occur the most in which combinations of 2 and 3.
• Add drill-down pie chart for grouped least significant "others". Large pie charts need to group very small entries into "others" to make the chart readable. To also know what is in that "others" group, there is now a separate drill-down chart showing e.g. all entries lower than 0.5% overall.
• Make Typescript scan heap memory configurable. For very large Typescript projects it might be needed to increase the 4096 MB default heap size. This is now possible by using the environment variable TYPESCRIPT_SCAN_HEAP_MEMORY given in megabyte.

⚙️ Optimization

• Improve Wordcloud for Typescript. Now, git data is excluded in the main WordCloud and a couple of stop words where added to make it more expressive. Additionally, there is now a separate WordCloud for git authors.
• Harmonize and optimize pie charts. Now, all (major) pie charts show percentages and absolute counts. They all also utilize explode plots for grouped "others" (e.g. less than 0.5% overall) entries.
