 * Read and write a target file. Unlike Okio's built-in `Okio.source(java.io.File file)` and `Okio.sink(java.io.File file)`
 * this class offers:
 *
 *  * **Read/write:** read and write using the same operator.
 *  * **Random access:** access any position within the file.
 *  * **Shared channels:** read and write a file channel that's shared between
