Allow updating holograms in bulk

Browse Source 
This improves performance when using *HolographicDisplays* drastically on many holograms.

Plugins like *EpicAnchors* might need to manage and update a lot of holograms frequently, causing SongodaCore to fetch all the holograms from the external API (My test setup reduced the time needed to update from ~30ms to ~1ms)
