Possible regression in version parsing

[chrsch-dev]

Hi,

since version 2.0.0 the behavior of the parsing of a purl did change:
For version <=1.2.0

PackageURL.fromString('pkg:npm/a@2%2B3').toString() produced `pkg:npm/a@2%2B3`

Since version 2.0.0 the output changed

PackageURL.fromString('pkg:npm/a@2%2B3').toString() produced `pkg:npm/a@2+3`

Was this change done by intention or is this a regression?

@chrsch-dev This is related to #52 and #54 as well. The + is allowed in things like query params. The purl spec is about a balance of human readable encoding and percent encoding. Refs:
