PureJSON still escapes output

Description

Trying to use PureJSON as described in the example works fine, but when using it in my app to format a database (sqlx + sqlite) response, it will always use the default JSON behaviour of escaping the e.g. "<" in HTML as \u003c.

Working as expected:

		c.PureJSON(200, gin.H{
			"html": "<b>Hello, world!</b>",
		})

Not working:

		data := struct {
			Thing model.Thing
		}{
			thing,
		}
		c.PureJSON(200, data)

Where thing is the scanned result of a sqlx db.Get
