DataOutput and DataInput support in FastByteArray streams

[magicprinc]

1. FastByteArrayOutputStream
   toString(Charset) as in ByteArrayOutputStream
   implements DataOutput (without IOException)

2. FastByteArrayInputStream
   fast in-memory implementation of all inherited methods
   implements DataInput (without IOException)

With this addition FastByteArray*Streams can be used instead of JDK ByteBuffer:
I see a lot of potential 🔥

String latin1text = "   latin1 text is ok";

var sms = new FastByteArrayOutputStream(160);
sms.writeByte(0);// udh len

sms.writeByte(IE_CONCATENATED_SHORT_MESSAGES_16BIT_REF);
sms.writeByte(4);// iel
sms.writeShort(12345);
sms.writeByte(2);
sms.writeByte(1);

sms.writeByte(IE_APPLICATION_PORT_ADDRESSING_SCHEME_16BIT_ADDR);
sms.write(4);
sms.writeShort(8080);
sms.writeShort(12728);

sms.array[0] = (byte)(sms.position() -1);

sms.writeBytes(latin1text);

assertEquals(
	"0c08043039020105041f9031b82020206c6174696e312074657874206973206f6b",
	toHex(sms.toByteArray())
);
//
var parse = new FastByteArrayInputStream(sms.toByteArray());
int len = parse.readByte();
assertEquals(12, len);
assertEquals(IE_CONCATENATED_SHORT_MESSAGES_16BIT_REF, parse.readByte());
assertEquals(4, parse.readUnsignedByte());// iel
assertEquals(12345, parse.readShort());
assertEquals(2, parse.readUnsignedByte());
assertEquals(1, parse.readUnsignedByte());

assertEquals(IE_APPLICATION_PORT_ADDRESSING_SCHEME_16BIT_ADDR, parse.readByte());
assertEquals(4, parse.readUnsignedByte());
assertEquals(8080, parse.readUnsignedShort());
assertEquals(12728, parse.readUnsignedShort());

assertEquals(latin1text, parse.readLine());// just as a bad example!

no IOException, no wrappers, out-of-box, primitive types friendly, compact and easy

I have 100% test coverage locally, but my unit tests need refactoring to push them to this high quality project.
And I feel more safe if you or somebody's "production" 😅 extra test this code.

PS:
This is my last PR 🥳
the quality of the fastutil is very high, and feature set is very rich ❤
I sent everything I have found
