Tiansuan Cubesat Space Protocol

Todo

There are some known problems need to address:

The bineary size is too large.
The crate should separate into at least 3 parts (tcsp-adaptor,tcsp-application,tcsp-protocol)
The naming of two frame structs is ambiguous. Rename it.
The size field in meta of adaptor::Frame should not be edited by user. Instead, providing an interface for user to update and read length of comming package.
Lacking of real hardware tests and benchmark.
Lacking of documents of protocol and a method to generate document for others to read.
The client side is not yet implemented.
