Feature: Add bulk split/join

[Justman100]

Example: We have the network 159.69.0.0/21... Now I want to split this in all possible /24 subnets at once... Or in /23... /22...

Or we take 159.69.0.0/16 and want to split this in all possible /18, /19, /22 etc

How would this ideally look?

Idea:

• You set 159.69.0.0/21 in the top bar and then go to Tools > Bulk Split.
• It gives you a modal with a dropdown of possible split options, so you choose /24.
• It splits every network larger than /24 into /24s, and leaves all smaller networks as-is?

You could conceivably do a bulk join as well, but in the current setup joined networks erase their contents if they differ (such as merging /18 "TestA" note with /18 "TestB" note into /17). If their colors/notes match then they are preserved, but if they differ it resets to white and no note. I could I guess apply the same logic here, so if you bulk joined everything to /24 but had a bunch of various network sizes under that they would all have to match contents (note/color), otherwise it would result in a blank /24.

Sounds good

Well, that's the way it has to be
