```
public static boolean isZstdCompressionAvailable()
```
    Are the classes required to support Zstandard compression available?
    
    Returns:
    
    true if the classes required to support Zstandard compression are available
  - matches
```
public static boolean matches(byte[] signature,
                              int length)
```
    Checks if the signature matches what is expected for a Zstandard file.
    
    Parameters:
    
    signature - the bytes to check
    
    length - the number of bytes to check
    
    Returns:
    
    true if signature matches the Ztstandard or skippable frame magic bytes, false otherwise
