Negligible lookup maps used for matching fingerprints have been removed to reduce the likelihood of OOM when the maps are instantiated, commonly observed with 400M RAM. Additionally, lookup maps previously kept for the duration of the patcher instance are now cleared before the classes are compiled. This reduces the likelihood of OOM when compiling classes. On a related note, a linear increase in memory usage is observed with every compiled class until all classes are compiled implying compiled classes not being freed by GC because they are still referenced. After compiling a class, the class is technically free-able though. The classes are assumed to be referenced in the `multidexlib2` library that takes the list of all classes to compile multiple DEX with and seems to hold the reference to all these classes in memory until all DEX are compiled. A clever fix would involve splitting the list of classes into chunks and getting rid of the list of all classes so that after every DEX compilation, the corresponding split of classes can be freed.
