Device Interface Improvements (Experiment/better_parsing)

[microstrain-sam]

Changes:

• mip_interface_recv_from_device no longer passes a buffer. Instead, user must call mip_interface_input_bytess with their own buffer of data.
• Parser constructor no longer requires/accepts a buffer (parser is now fully stand-alone).
• Removed optional limit on max packets per parse call. User can instead limit number of bytes sent to the parser.
• mip_parser_parse and related functions return void because they always consume the entire buffer.
• Parser callback now must return void (early abort not supported anymore as its probably not that useful)
• Parser performance improvements (reduced copying, use memcpy, memchr)
• Updated examples/tests accordingly.
