Implementation of first verion of this gem based mostly on @huyha85's opengraph_parser https://github.com/huyha85/opengraph_parser and its forks:
Charset support taken from @codefist fork: https://github.com/codefirst/opengraph_parser
I prefer to make my own repo for this gem as origin repo is seemingly-abandoned and I need more functionality than just opengraph (ogp.me) tags parsing.
