Column sorting should be done using stable sort implementation

Describe the bug
I cannot compose column sorting in SizeBench, because it uses unstable sorting for sorting by column.

What you are doing

1. Open a binary for inspection
2. Select "Start Exploring By Compilands"
3. Sort results by specific column, e.g. Size on Disk
4. Sort results by different column, e.g. Lib Name

Expected behavior
I want the rows to be sorted by Lib Name and within single lib, by their size on disk.

What actually happens is that I get rows sorted by Lib Name and otherwise jumbled, so I can't go after largest obj files in given lib, which is what I want to do.

Environment Details

• OS: [type ver at the Windows Command Prompt]: [Version 10.0.19044.1889]
• SizeBench version number [Go to Help > About SizeBench]: 2.2204.1800.0 (git commit b5c2b2ea)

Additional context
While my original use case is specifically grouping by lib, sort by size on disk, using stable sort when sorting by column will allow users to compose their own sorting orders arbitrarily.

Reproduce the issue through Start Exploring By Compilands by sorting first on Size on Disk and then on Lib Name. Locate the column-sorting implementation and make the composed order preserve the earlier sort within equal later-sort values; done means the rows remain ordered by size within each library.
