Animated tiles must be adjacent in the tileset

[adrien-bon]

This limitation comes from bevy_ecs_tilemap.

Right now, we use the bevy_ecs_tilemap::tiles::AnimatedTile struct which is defined as follow:

pub struct AnimatedTile {
    /// The start frame index in the tilemap atlas/array (inclusive).
    pub start: u32,
    /// The end frame index in the tilemap atlas/array (exclusive).
    pub end: u32,
    /// The speed the animation plays back at.
    pub speed: f32,
}

We only get a start and an end indexes which implies tiles are next to each other in the tileset.

Possible work-around:

• update the tileset to make sure tiles are adjacent
• as stated in this issue, we could overcome this by creating our own animation system but it feels a bit out of scope for this crate
