bevy_tileset_core needs local dependency which is not in repo

[YegorStolyarov]

In bevy_tileset_core/Cargo.toml I have to replace bevy_tile_atlas = { path = "../../bevy_tile_atlas", version = "0.7" } with bevy_tile_atlas = "0.7.0" to fix cargo issue and run examples. Consider using cates.io dependency.
