#### compress(buffer[, zstdCompressParams], callback)
`javascript

#### decompress(buffer[, zstdDecompressParams], callback)
`javascript

`
#### compressSync(buffer[, zstdCompressParams])
`javascript

#### compressStream([zstdCompressParams])
`javascript
const compressStream = require('cppzst').compressStream;
const fs = require('fs');
fs.createReadStream('path/to/input')
.pipe(compressStream())
.pipe(fs.createWriteStream('path/to/output'));

#### decompressStream([zstdCompressParams])
`javascript
const decompressStream = require('cppzst').decompressStream;

`
The compress, compressSync and compressStream methods may accept an optional zstdCompressParams object to define compress level and/or dict.
`javascript`
const zstdCompressParams = {
level: 5, // default 1
dict: new Buffer('hello zstd'), // if dict null, left level only.
dictSize: dict.length // if dict null, left level only.
};
The decompress, decompressSync and decompressStream methods may accept an optional zstdDecompressParams object to define dict.
`javascript`
const zdtdDecompressParams = {
dict: new Buffer('hello zstd'),
dictSize: dict.length
};
