* chore: factor out rdb_load utilities into separate files rdb_load.cc is huge and contains many auxillary classes. This PR moves DecompressImpl and ErrorRdb code into detail/ It also fixes minor bugs around error conditions with de-compression: a. Do not check-fail on invalid opcode and return error_code instead. b. Print correctly LZ4 errors.
