Let us move Allays

The Allay is a great mob, and for its intended purpose, it works very well. However, there's one pretty big issue I noticed while playing there is no good natural way to transport them. The Allay will always be left behind if the player moves away too fast, which when the player gets ahold of the elytra, losing your Allay becomes easy. Thus I suggest implementing a way to catch them in some way. This could be in the form of a little cage, but this would require a new item to be added, so maybe we could be able to use glass bottles or even buckets (Bucket of Allay would be kind of hilarious). Or since they seem to have some connection to amethyst maybe we could infuse them into shards and when you let it out the shard breaks or disappears making it more balanced in my opinion. If this was in any way implemented using the Allays would be much simpler.

Please tell me what you think about this idea!
