absl::WebSafeBase64Unescape

Converts a src string encoded in "web safe" Base64 (RFC 4648 section 5) to its binary equivalent, writing it to a dest buffer, returning true on success. If src contains invalid characters, dest is cleared and returns false. If padding is included (note that WebSafeBase64Escape() does not produce it), it must be correct. In the padding, '=' and '.' are treated identically.
