ReaderConfig

Configuration for com.github.plokhotnyuk.jsoniter_scala.core.JsonReader that contains flags for tuning of parsing exceptions and preferred sizes for internal buffers that created on the reader instantiation and reused in runtime for parsing of messages.
All configuration params already initialized by recommended default values, but in some cases they should be altered for performance reasons:

turn off stack traces for parsing exceptions to greatly reduce impact on performance for cases when exceptions can be not exceptional (e.g. under DoS attacks over open to the world systems), see more details here: https://shipilev.net/blog/2014/exceptional-performance/
turn off appending of hex dump to minimize length of exception message
increase preferred size of an internal char buffer to reduce allocation rate of grown and then reduced buffers when large (>1Kb) string instances need to be parsed
increase preferred size of an internal byte buffer for parsing from java.io.InputStream or java.nio.DirectByteBuffer to reduce allocation rate of grown and then reduced buffers during parsing of large (>16Kb) scala.math.BigDecimal, scala.math.BigInt or ADT instances with the discriminator field doesn't appear in the beginning of the JSON object

throwReaderExceptionWithStackTrace: a flag that allows to turn on a stack traces for debugging purposes in development
appendHexDumpToParseException: a flag that allows to turn off hex dumping of affected by error part of an internal byte buffer
preferredBufSize: a preferred size (in bytes) of an internal byte buffer when parsing from java.io.InputStream
preferredCharBufSize: a preferred size (in chars) of an internal char buffer for parsing of string values
