/*
Package inetcksum applies the "Internet Checksum" algorithm as specified/described in:

	* [RFC 1071]
	* [RFC 1141]
	* [RFC 1624]

It provides [InetChecksum], which can be used as a:

	* [hash.Hash]
	* [io.ByteWriter]
	* [io.StringWriter]
	* [io.Writer]
	* [io.WriterTo]

and allows one to retrieve the actual bytes that were checksummed.
It is also fully concurrency-safe.

There is also an [InetChecksumSimple] provided, which is more
tailored for performance/resource usage at the cost of no concurrency
safety and no data retention, which can be used as a:

	* [hash.Hash]
	* [io.ByteWriter]
	* [io.StringWriter]
	* [io.Writer]
