Adam Lesinski f90f2f8dc3 Support multiple resource tables with same package
In order to support APK split features, the resource
table needs to support loading multiple resource
tables with the same package but potentially new set
of type IDs.

This adds some complexity as the type ID space changes
from dense and ordered to potentially sparse.

A ByteBucketArray is used to store the type IDs in
a memory efficient way that allows for fast retrieval.

In addition, the IDMAP format has changed. We no longer
need random access to the type data, since we store the
types differently. However, random access to entries of
a given type is still required.
