feat: Introduce BooleanT and boolean functions (#17) This PR adds a boolean section, as well as an isNaN predicate on numbers. In a TypeDispatcher, when BooleanT is present, isNaN returns a BooleanT. However, in a numbers-only TypeDispatcher, it returns 1 or 0 instead. Moreover, when booleans are subsequently added to a numbers-only instance, isNaN properly reconfigures itself to return BooleanT. No predicates that depend on approximate equality testing or a configuration object are implemented in this PR. This PR also implements type matching and dispatching with implicit conversions, and adds an implicit conversion from BooleanT to NumberT.
