ee_install in windows new R version incompatible with py_discover_config()[["version"]] returning non character class

[fpirotti]

ee_install not works in Windows because in utils::compareVersion(py_version, "3.5") is returns error
Error in strsplit(a, "[.-]") : non-character argument
due to line with py_version <- py_discover_config()[["version"]] returning not a character but a class "package_version" "numeric_version" this should be fixed by simply changing to
utils::compareVersion(as.character(py_version), "3.5")
