import { isSemVer } from "https://deno.land/std@0.199.0/semver/is_semver.ts";
Checks to see if value is a valid SemVer object. It does a check into each field including prerelease and build.
Some invalid SemVer sentinels can still return true such as ANY and INVALID. An object which has the same value as a sentinel but isn't reference equal will still fail.
Objects which are valid SemVer objects but have extra fields are still considered SemVer objects and this will return true.
A type assertion is added to the value.
