CRC

### Motivation

Implement a flexible, configurable CRC generator component

### Desired solution

See https://en.wikipedia.org/wiki/Cyclic_redundancy_check

The CRC generator should be extremely configurable to generate practically any CRC that may be needed. Some configurability that would be nice:
- Different ways to construct it (e.g. normal, reversed, reciprocal, reversed reciprocal, list of polynomials, etc.)
- Pre-configured flavors available for popular CRC polynomials
- Configurable pipelining (e.g. all in one cycle or pipelined across a configurable number of cycles)

It should be able to both generate and check CRC.
