-/** Fibonacci Linear Feedback Shift Register (LFSR) generator.
-  *
-  * A Fibonacci LFSR can be generated by defining a width and a set of tap points (corresponding to a polynomial). An
-  * optional initial seed and a reduction operation ([[XOR]], the default, or [[XNOR]]) can be used to augment the
-  * generated hardware. The resulting hardware has support for a run-time programmable seed (via [[PRNGIO.seed]]) and
-  * conditional increment (via [[PRNGIO.increment]]).
-  *
-  * $seedExplanation
-  *
-  * In the example below, a 4-bit Fibonacci LFSR is constructed. Tap points are defined as four and three (using LFSR
-  * convention of indexing from one). This results in the hardware configuration shown in the diagram.
-  *
-  * {{{

-  * If you require a maximal period Fibonacci LFSR of a specific width, you can use [[MaxPeriodFibonacciLFSR]]. If you
-  * only require a pseudorandom [[UInt]] you can use the [[FibonacciLFSR$ FibonacciLFSR companion
-  * object]].
