Common: * wrap dictionary data into `BrotliDictionary` structure * replace public constant with getter `BrotliGetDictionary` * reformat dictionary data Decoder: * adopt common changes * clarify acceptable instance usage patterns * hold reference to dictionary in state Encoder: * adopt common changes * eliminate PIC spots in `CreateBackwardReferences` * add per-chunk ratio guards for q0 and q1 * precompute relative distances to avoid repeated calculations * prostpone hasher allocation/initialization * refactor Hashers to be class-like structure * further improvements for 1MiB+ inputs * added new hasher type; made hashers more configurable Java: * Pull byte->int magic to `IntReader` from `BitReader`
