Implement new way to generate boosters using box mapping info (WIP) (#7529)

* [THB] added initial common/uncommon collation mechanism

* [THB] added rare/mythic and lands to pack generation

* fixed some card names

* broke out collation into its own separate classes

* built collation into ExpansionSet

* added note about collation information

* [KHM] added collation info

* updated collation to use collector number rather than name

* added shuffle to set constructor

* added some notes on collation methods
