EntityStorageInfoLookup An dictionary-like object that provides access to information about how Entities are stored, indexed by Entity.
Manually gets an EntityStorageInfoLookup object that can access a EntityStorageInfo.
Remember to call EntityStorageInfoLookup.Update.
Assign the returned object to a field of your Job struct so that you can access the
contents in a Job.
Prefer using SystemAPI.GetEntityStorageInfoLookup as it will cache in OnCreate for you
and call .Update(this) at the call-site.
