Anki add-on: Faster Editor

Each time Anki opens the editor, it launches a new instance. On Windows, this means that the editor takes about a second to open, and a bit longer to have the information ready. This addon opens the editor in the background on startup (or first time the editor opens), and hides the editor on save, allowing it to be opened more quickly. Extra Details: Benchmark: On my Windows 11 PC, I ran a simple AHK script to benchmark how fast Anki could open/close the editor in a loop. In 10 seconds, it opened it 12 times at the fastest, but usually about 8 (among all video drivers). With Faster Editor, this benchmark jumped to 28 times in 10 seconds. Though this seems like a ~3x increase in performance, its actually even more quick than that. During the test, the editor did not have text rendered each time it was opened/closed - even with a basic card - meaning that it is actually slower than that for the new instance to completely initialize.
