Move getLength to address length (not address length + 1), as we're explicitly saturating in order to express as a normal address.

Don't unseal caps in setBounds
...
I'm not sure why this was here, as setBounds on a sealed cap would previously cause a trap anyway.
Maybe left over from when otype bits were shared with the bounds?

New function for adding to the address unsafely.

Would used an increment size based on mantissa width, but this is not
available in the type class, so just use 1 byte.
This function is currently used for adding small increments to the PC,
so does not need support for larger offsets.
