Unable to construct PURL containing percent signs

Or worse if the percent sign is followed by two or more hex characters:

> new PackageURL("generic", "", "%21").toString();
'pkg:generic/!'

It only works correctly for qualifier values:

> new PackageURL("generic", "test", "test", "1.0", {"a": "100%"}).toString();
'pkg:generic/test/[email protected]?a=100%25'

@matt-phylum Thanks for the find! This happens because in v2 normalization is consistent across constructor and fromString. In v1.x PackageURL.fromString("pkg:general/100%/test") would throw a similar error (because of decodeURIComponent use).
