For fun I made a scanner rule that forces BinaryInteger to
conform to a power of 2 grouping of nibbles. I think it loses
it's clarity after 16 bits.
I made the underscore optional between nibbles, but required for
groups of 2 bytes and above.
Some passing cases from my test inputs.
0b00010001
0b0001_0001
0b00010001_0001_0001
0b00010001_00010001
0b0001_0001_00010001
0b00010001_00010001
0b00010001_00010001_00010001_00010001
0b00010001_00010001_00010001_00010001_00010001_00010001_00010001_00010001
0b00010001_00010001_00010001_00010001_00010001_0001_0001_00010001_00010001_00010001_00010001_00010001_00010001_00010001_00010001_00010001_00010001
It loses some of the value of arbitrary grouping specifically the
ability to group bits in a bitmask by function.
