High memory usage when adding region annotation with huge link

[rchl]

Description of the bug

Creating region annotation using view.add_regions() with a huge link (1MB, for example) results in ST using more than 30GB of memory (hard to say exactly how much as I don't have that much RAM).

Steps to reproduce

1. Start in safe mode
2. Create a plugin (note that this includes about 1MB of text): https://gist.github.com/rchl/4d2745ad56475690f4d771d089dfbece
3. Change caret position in a file

Expected behavior

Not blow up due to high memory usage

Actual behavior

Uses more than dozen GB of RAM while creating annotation
