feature: Save Editor tab group in Explorer and bring up those tab groups whenever needed

[ashuvssut]

I sometimes work on multiple feature branches at a time.
For each feature, I need certain editor tab to be opened up.

For details, lets take an example

• I have 2 feature branches F1, & F2
• when I am on F1, I opened 5 files in my editor.
• Now i want to work on F2. Instead of closing all those 5 F1 editor tabs, I would like to save that editor tab group in my Explorer or somewhere.
• Now after saving that editor group, I will close all 5 of them.
• i can now start working on F2 with a clean editor space. I will open (say) 7 editor tabs for working on F2
• Now if I want to switch to F1, I will save my current 7 editor tabs into a group.
• Now I will open the Explorer again to bring up my saved F1 tab group
