vendor: xeipuuv/gojsonschema v1.2.0

full diff: https://github.com/xeipuuv/gojsonschema/compare/v1.1.0...v1.2.0

- Fix a race condition when registering new formats.
- Improve the performance of uniqueItems.
- Fix an issue where integers would be shown as a fraction
- Require format to be of type string and formats can now be registered after a schema is parsed.
- Improve the handling of true and false schema.
- Fix an issue where an invalid schema would cause a panic.
- Properly handle file URIs that contain spaces.

@@ -343,7 +344,7 @@ Not all formats defined in draft-07 are available. Implemented formats are:
 `email`, `uri` and `uri-reference` use the same validation code as their unicode counterparts `idn-email`, `iri` and `iri-reference`. If you rely on unicode support you should use the specific 
 unicode enabled formats for the sake of interoperability as other implementations might not support unicode in the regular formats.
 
-The validation code for `uri`, `idn-email` and their relatives use mostly standard library code. Go 1.5 and 1.6 contain some minor bugs with handling URIs and unicode. You are encouraged to use Go 1.7+ if you rely on these formats.
+The validation code for `uri`, `idn-email` and their relatives use mostly standard library code.
 
 For repetitive or more complex formats, you can create custom format checkers and add them to gojsonschema like this:
