(conan-io#8375) Feature/add ofeli

* add ofeli library

* follow pep8

* follow conan hooks

* set compiler to c++11

* add c++ 11 standard to test_package

* set supported compiler

* check os for setting compiler

* remove stdc++11 from conanfiles

* check min cppstd and add debug or release build type choose

* test with config_options

* remote stdc++11 cppstd_flag and update license

* check libstdc++ ABI support
