HTTP status 1xx responses (Continue) are not supported

[jrnk]

See issue #593 and #592 , this issue is still present in the 5.0 release

This code should be in the 5.0 release (from the release notes), but it's missing:

See f.e. on_message_complete on that supposedly merged commit https://github.com/httprb/http/blob/46a52dcf0bb891ccddfe49413c93bc5be295fcf9/lib/http/response/parser.rb#L88

And the one in the 5.0 release: https://github.com/httprb/http/blob/v5.0.0/lib/http/response/parser.rb#L114

@ixti was this reverted?

[ixti]

https://github.com/httprb/http/pull/651 introduced the regression. Will work on this.
