improve AssetManager implementation (#728)
* improve AssetManager implementation

Notable changes are:
 * removed the individual managers inside of d2asset, only one asset manager
 * AssetManager now has caches for the types of files it loads
 * created a type for TextDictionary (the txt file structs)
 * fixed a file path bug in d2loader Source
 * fixed a asset stream bug in d2loader Asset
 * d2loader.Loader now needs a d2config.Config on creation (for resolving locale files)
 * updated the mpq file in d2asset test data, added test case for "sub-directory"
 * added a Data method to d2asset.Asset. The data is cached on first full read.
 * renamed ArchiveDataStream to DataStream in d2interface
 * moved palette utility func out of d2asset and into d2util
 * bugfix for MacOS mpq loader issue

* minor lint fixes

* removed obsolete interfaces from d2interface

* lint fixes, added data caching to filesystem asset

* adding comment for mpq asset close

* adding comment for mpq asset close
