Modernize (#149)
* add .clang-format for automated code formatting * automatic code formatting * move config.mk below all target to allow custom non-default build targets * add license to the top of the file * use correct header file guards syntax * convert to single-header, header-only library * update makefile to use jsmn as a header-only library * update readme * add changed from PR #143 * fix clang warnings * add changes from PR #142 * add consts as per PR #134master v1.1.0
