Subject: [PATCH] Constrain to pytket 1.x. (#187)

When we release pytket 2.0 the `ClassicalExpBox` and
`add_classicalexpbox_{bit,register}` will disappear. After that it
should be a simple matter to update the requirement to ">= 2.0.0" and
remove the handling of, and tests involving, `ClassicalExpBox` in this
repo.
