Fixed

• #140 fixes retrieval of headers when multiple headers of the same name
  are added to the Headers instance; it now ensures that the last header added of the same
  type is retrieved when it is not a multi-value type. Previous values are overwritten.

• #112 provides performance improvements when parsing large chunked messages.

• introduces changes to Response::fromString() to pull the next line of the response
  and parse it for the status when a 100 status code is initially encountered, per https://tools.ietf.org/html/rfc7231\#section-6.2.1

• #122 fixes an issue with the stream response whereby if the outputstream
  option is set, the output file was opened twice; it is now opened exactly once.

• #147 fixes an issue with header retrieval when the header line is malformed.
  Previously, an exception would be raised if a specific HeaderInterface implementation determined
  the header line was invalid. Now, Header::has() will return false for such headers, allowing
  Request::getHeader() to return false or the provided default value. Additionally, in cases
  where the header name is malformed (e.g., Useragent instead of User-Agent, users can still
  retrieve by the submitted header name; they will receive a GenericHeader instance in such
  cases, however.

• #133 Adds back missing
  sprintf placeholder in CacheControl exception message
