Aseprite Atlas repeat value to follow editor convention

[MondayHopscotch]

• Flixel version: 5.4.1

---

Aseprite editor behavior is as follows:

Tag's Repeat Checkbox	Tag's Repeat Field Value	Tag Looping behavior
- [ ] Repeat	N/A	Loops Forever
- [x] Repeat	1	Plays a single time, stopping at the final frame
- [x] Repeat	>1	Plays N times

Currently, AseAtlas parses the loops value as:

inline function get_loops()
{
	return this != null && toInt() > 0;
}

However, in the Aseprite editor, tags default to looping, represented by the Repeat field on the tag being unchecked.

Current Flixel parsed behavior:

Tag's Repeat Checkbox	Tag's Repeat Field Value	Flixel Animation parsed loops value
- [ ] Repeat	N/A	false
- [x] Repeat	1	true
- [x] Repeat	>1	true

Desired Flixel parsed behavior:

Tag's Repeat Checkbox	Tag's Repeat Field Value	Flixel Animation parsed loops value
- [ ] Repeat	N/A	true
- [x] Repeat	1	false
- [x] Repeat	>1	true

With this behavior, the only gap between Aseprite and Flixel is in the case where Repeat is >1, as Flixel does not have a built-in notion of playing an animation x times.
