DeflaterEstimatorLz4 (PNGJ 2.1.0 API)

```
public final class DeflaterEstimatorLz4
extends Object
```
This estimator actually uses the LZ4 compression algorithm, and hopes that it's well correlated with Deflater. It's about 3 to 4 times faster than Deflater. This is a modified heavily trimmed version of the net.jpountz.lz4.LZ4JavaSafeCompressor class plus some methods from other classes from LZ4 Java library: https://github.com/jpountz/lz4-java , originally licensed under the Apache License 2.0

Methods
Modifier and Type	Method and Description
`int`	`compressEstim(byte[] src)`
`int`	`compressEstim(byte[] src, int srcOff, int srcLen)` Estimates the length of the compressed bytes, as compressed by Lz4 WARNING: if larger than LZ4_64K_LIMIT it cuts it in fragments WARNING: if some part of the input is discarded, this should return the proportional (so that returnValue/srcLen=compressionRatio)
