MarkUtils-IO: Performant Java Streams, Readers, and Writers

MarkUtils-IO is another high-performance addition to MarkUtils, and is a collection of utility classes that I've found myself frequently reusing over the past number of years.

• AppendableWriter: A faster alternative to StringWriter. Uses a non-synchronized StringBuilder by default instead of the synchronized StringBuffer, but also accepts any Appendable as the underlying destination.
• CharSequenceReader: An alternative to StringReader, but supports reading from any CharSequence in addition to String. Optimizations included for String, StringBuilder, StringBuffer, and CharBuffer.
• NoFlushBufferedOutputStream, NoFlushBufferedWriter: Fixes / work-arounds for https://issues.apache.org/jira/browse/XALANJ-2500. Overrides flush() to do nothing, unless called as flush(boolean) with true. (Previously discussed: Xalan-J Serialization Performance hindered by Flushing.)
• OutputStreamSplitter, WriterSplitter: Writes to zero or more OuputStreams or Writers as one.
• RandomAccessFileInputStream, RandomAccessFileOutputStream: Provides an InputStream or an OutputStream from a RandomAccessFile.

Work on this library was also the driving factor for another recent post concerning some of Java's built-in code, Redundant argument validation code in Java IO classes.
