Subject: [PATCH] Drop `is.value()` (#187)

Since it's never used and `evaluate()` doesn't produce an object of this type.

 # evaluate (development version)
 
+* `is.value()` has been removed since it tests for an object that evaluate never creates.
 * `parse_all()` no longer has a default method, which will generate better errors if you pass in something unexpectected.
 * The package now depends on R 4.0.0 in order to decrease our maintenance burden.
 * `evaluate()` automatically strips calls from conditions emitted by top-level code (these incorrectly get calls because they're wrapped inside `eval()`) (#150).
