v1.2.0

In this release there were minor miscellaneous typing improvements, but the bigger change is the way functions are normalized and typed.

Previously most Prague helpers returned a type of the form Transform<ARGS, RESULT> which really meant (...args: ARGS) => Promise<RESULT>. It was unwieldy to support a type name for such a simple concept, and ultimately unnecessary. Goodbye, Transform, we hardly knew ya.

In addition, there was a change to the handling of undefined results from Prague transforms. Previously these were normalized to null via the from function. Now they pass through unchanged. That means if your code used to say:

if (result === null)
    // do something

You now need to say:

if (result == null)
    // do something

This is a shorter way of saying:

if (result === null || result === undefined)
    // do something

The from function now just ensures that your function returns a Promise.
