Sort lines (case interleaved)

[robertefry]

Can you add sorting which is case-insensitive ascending, but ties are resolved by case.

For example; the following lines

Carrot
blue
alarm
Apple
Banana
Apricot

are sorted into

Apple
Apricot
alarm
Banana
blue
Carrot

Apricot is sorted after Apple, because ..r.... is lexicographical after ..p...
alarm is sorted after Apricot, because a.... is lowercase and A...... is uppercase.

If I have the time, I will look into making VSCode extensions, and try to send a merge request :)
