README

Get bit representation of a byte

When based on strings, %b directive of the fmt package provides a bit display. But it requires to range on chars which is prohibitive compared to other methods.

Rotating the bits each time introduces some penalty.

The simplest code is using the bits package and is marginally more efficient.
