Explicit depenancy doesn't exist inside lit-html@0.14.0

[xXACCEXx]

Looks like a reference to the lit-html doesn't exist in the 0.14.0 (latest at time of writing) version of the package, but your package denotes that it is fine to work with ^0.8, supporting any minor update, up to (not including) v1 of lit-html.

The reference I am struggling with is lit-html/lib/lit-extended.js which looks to have been dropped from lit-html@0.11.0 onwards.

Also, there is now a release candidate for lit-html@1, might be worth looking into that too?
