> Adds a new `ofFileChannel(FileChannel channel, long offset, long length)`
> method to `java.net.HttpRequest.BodyPublishers` to provide an `HttpClient`
> publisher to upload a certain region of a file. The new publisher does not
> modify the state of the passed `FileChannel`, streams the file channel bytes
> as it publishes (i.e., avoids reading the entire file into the memory), and
> can be leveraged to implement sliced uploads. As noted in the Javadoc:
>
>> The file channel will not be closed upon completion. The caller is
>> expected to manage the life cycle of the channel, and close it
>> appropriately when not needed anymore.
>
> ### Implementation notes
>
> - `FileChannel` is preferred over `{Readable,Seekable}ByteChannel`, since the
> latter does not provide a positional read without modifying the state of the
> `FileChannel`, which is necessary to use a single `FileChannel` instance to
> implement sliced uploads.
> - `ofFileChannel(FileChannel,long,long)` is preferred over
> `ofPath(Path,long,long)` to avoid overloading the maximum file descriptor
> limit of the platform.
