Update uriparser to 0.9.1.

>>>>>>>>>>>>> SECURITY >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
  * Fixed:
      Out-of-bounds read in uriParse*Ex* for incomplete URIs with IPv6
      addresses with embedded IPv4 address, e.g. "//[::44.1";
      mitigated if passed parameter <afterLast> points to readable memory
      containing a '\0' byte.
      Thanks to Joergen Ibsen for the report!
>>>>>>>>>>>>> SECURITY >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
  * Fixed: When parsing a malformed URI with an IPvFuture address
      (e.g. "http://[vA.123456" missing "]"), errorPos would point to the first
      character after "v" than the actual position of the error (here: the end
      of the string)
  * Fixed: uriToStringCharsRequired* reported 1 more byte than actually needed
      for IPv4 address URIs (GitHub #41); Thanks to @gyh007 for the patch!
  * Fixed: Compilation with MinGW
      Thanks to Sandro Mani for the patch!
  * Fixed: Drop use of asprintf from the test suite for MinGW (GitHub #40)
  * Improved: For parse errors, waterproof errorPos <= afterLast
  * Soname: 1:24:0
