Allow multiple comments on a single line

[islamaliev]

When doing a code review sometimes it's necessary to add several not related comments to a single line of code. Each of those should be resolvable separately.

At the moment only 1 commend is possible in the VSCode plugin.

Just spent half an hour trying left-click, right-click, click on different parts of the line, Cmd-Shift-P looking for how to add a comment to a line that someone else had already commented on. Finally went to the web to do it, and then thought I'd log an issue about this, and found that someone else already did, a year and a half ago.
