Add support for string types

- strings are now generated as two fields for length and string itself
- aliases are now sorted by name to prevent generating different code
- dependencies are now managed by dep
- binapi files are regenerated using VPP 19.01-rc0~622-g7b01e9e8
- old stats binary api has been deprecated and removed from VPP
